Let's divide 661757 by 68
The aim is to understand the frequency of 68 in 661757.

Advancing to step 1:
68 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 68

On to step 2:
68 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 68

On to step 3:
If we divide 661 by 68, we get 9 and a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 612 from 661 to get 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 68

On to step 4:
When dividing 497 by 68, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtracting 476 from 497 leaves us with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 68

On to step 5:
215 divided by 68 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 973.0
Subtracting 204 from 215 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 68

On to step 6:
117 divided by 68 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 9731.0
Subtracting 68 from 117 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
If we divide 490 by 68, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 9731.7
Subtracting 476 from 490 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 68, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 9731.72
Subtract 136 from 140 to 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 9:
If we divide 40 by 68, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9731.72
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 68, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 9731.7205
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
68 goes into 600 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 9731.72058
If we take 544 away from 600, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
The number 68 fits into 560 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 9731.720588
Subtracting 544 from 560 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 9731.720588 and a remainder of 1.6e-06.
