We look at the division of 83706842 by 712 
The aim is to understand the frequency of 712 in 83706842.

Advancing to step 1:
The number 712 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 712

Going ahead to step 2:
If we divide 83 by 712, we get 0 and a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 712

On to step 3:
If we divide 837 by 712, we get 1 and a remainder of 125.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 712 from 837 and we're left with 125.
Grab the next digit (0) from the dividend, add it to 125, then carry on: 1250 / 712

Advancing to step 4:
712 goes into 1250 1 times with a remainder of 538.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 712 away from 1250, we end up with 538.
Fetch the next digit (6) from the dividend, attach it to 538 and continue: 5386 / 712

On to step 5:
712 can be fit into 5386 7 times, resulting in a remainder of 402.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 4984 from 5386 and we're left with 402.
Grab the next digit (8) from the dividend, add it to 402, then carry on: 4028 / 712

Let's proceed to step 6:
When dividing 4028 by 712, we get 5 with a remainder of 468.
Write down 5 as next digit of the result. 
Result so far: 1175.0
Subtract 3560 from 4028 to get 468.
Grab the next digit (4) from the dividend, add it to 468, then carry on: 4684 / 712

On to step 7:
The number 712 fits into 4684 6 times, leaving a remainder of 412.
The number 6 becomes the next digit in our result. 
Result so far: 11756.0
If we subtract 4272 from 4684, we get 412.
Append the next digit (2) from the dividend to 412 and continue with: 4122 / 712

Moving on to step 8:
The number 712 fits into 4122 5 times, leaving a remainder of 562.
Write down 5 as next digit of the result. 
Result so far: 117565.0
Deduct 3560 from 4122 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 9:
When dividing 5620 by 712, we get 7 with a remainder of 636.
Write down 7 as next digit of the result. 
Result so far: 117565.7
If we take 4984 away from 5620, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 10:
The number 712 fits into 6360 8 times, leaving a remainder of 664.
Record the quotient 8 as the next digit in the result. 
Result so far: 117565.78
Deduct 5696 from 6360 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Going ahead to step 11:
6640 divided by 712 is 9 with a remainder of 232.
Write down 9 as next digit of the result. 
Result so far: 117565.789
The remainder is 232 after subtracting 6408 from 6640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 12:
2320 divided by 712 is 3 with a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 117565.7893
Deduct 2136 from 2320 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 13:
When dividing 1840 by 712, we get 2 with a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 117565.78932
Deduct 1424 from 1840 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 14:
The number 712 fits into 4160 5 times, leaving a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 117565.789325
The remainder is 600 after subtracting 3560 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 15:
The number 712 fits into 6000 8 times, leaving a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 117565.7893258
If we take 5696 away from 6000, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 16:
712 goes into 3040 4 times with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 117565.78932584
Deduct 2848 from 3040 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 117565.78932584 with a remainder of 1.92e-07.
