We look at the division of 77741490 by 846 
The aim is to understand the frequency of 846 in 77741490.

Advancing to step 1:
When dividing 7 by 846, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 846

Advancing to step 2:
846 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 846

Going ahead to step 3:
The number 846 fits into 777 0 times, leaving a remainder of 777.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 777 to get 777.
Append the next digit (4) from the dividend to 777 and continue with: 7774 / 846

Moving on to step 4:
846 goes into 7774 9 times with a remainder of 160.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 7614 from 7774, we get 160.
Include the next digit (1) from the dividend after 160, then repeat: 1601 / 846

Advancing to step 5:
If we divide 1601 by 846, we get 1 and a remainder of 755.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we take 846 away from 1601, we end up with 755.
Grab the next digit (4) from the dividend, add it to 755, then carry on: 7554 / 846

Let's proceed to step 6:
If we divide 7554 by 846, we get 8 and a remainder of 786.
Put 8 as the next digit of the answer. 
Result so far: 918.0
Deduct 6768 from 7554 and we're left with 786.
Fetch the next digit (9) from the dividend, attach it to 786 and continue: 7869 / 846

Let's proceed to step 7:
846 goes into 7869 9 times with a remainder of 255.
Use 9 as the next digit of our solution. 
Result so far: 9189.0
Subtracting 7614 from 7869 leaves us with 255.
Include the next digit (0) from the dividend after 255, then repeat: 2550 / 846

Let's proceed to step 8:
When dividing 2550 by 846, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 91893.0
Deduct 2538 from 2550 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
If we divide 120 by 846, we get 0 and a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 91893.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
1200 divided by 846 is 1 with a remainder of 354.
Record the quotient 1 as the next digit in the result. 
Result so far: 91893.01
If we subtract 846 from 1200, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 11:
3540 divided by 846 is 4 with a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 91893.014
Subtracting 3384 from 3540 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 12:
1560 divided by 846 is 1 with a remainder of 714.
The next digit of our result is 1. 
Result so far: 91893.0141
If we take 846 away from 1560, we end up with 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Step 13:
7140 divided by 846 is 8 with a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 91893.01418
The remainder is 372 after subtracting 6768 from 7140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 14:
If we divide 3720 by 846, we get 4 and a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 91893.014184
Subtract 3384 from 3720 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 15:
If we divide 3360 by 846, we get 3 and a remainder of 822.
Record the quotient 3 as the next digit in the result. 
Result so far: 91893.0141843
Subtracting 2538 from 3360 leaves us with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Step 16:
The number 846 fits into 8220 9 times, leaving a remainder of 606.
Write down 9 as next digit of the result. 
Result so far: 91893.01418439
If we take 7614 away from 8220, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Our division results in 91893.01418439 with a remaining 6.06e-07.
