671987 divided by 68 
The aim is to understand the frequency of 68 in 671987.

Advancing to step 1:
6 divided by 68 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 68

Let's proceed to step 2:
If we divide 67 by 68, we get 0 and a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 68

Advancing to step 3:
When dividing 671 by 68, we get 9 with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 612 from 671, we get 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 68

On to step 4:
If we divide 599 by 68, we get 8 and a remainder of 55.
The next digit of our result is 8. 
Result so far: 98.0
If we take 544 away from 599, we end up with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 68

Moving on to step 5:
If we divide 558 by 68, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 988.0
Deduct 544 from 558 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 68

Step 6:
68 can be fit into 147 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 9882.0
The remainder is 11 after subtracting 136 from 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
68 can be fit into 110 1 times, resulting in a remainder of 42.
The next digit of our result is 1. 
Result so far: 9882.1
If we take 68 away from 110, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
The number 68 fits into 420 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 9882.16
Subtracting 408 from 420 leaves us 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.

Moving on to step 9:
When dividing 120 by 68, we get 1 with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 9882.161
If we subtract 68 from 120, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
520 divided by 68 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 9882.1617
If we take 476 away from 520, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
68 goes into 440 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 9882.16176
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 68, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 9882.161764
If we take 272 away from 320, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
68 can be fit into 480 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 9882.1617647
If we subtract 476 from 480, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 68, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9882.1617647
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 9882.1617647 with a remainder of 4e-08.
