We look at the division of 68638710 by 747 
The aim is to understand the frequency of 747 in 68638710.

On to step 1:
747 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 747

On to step 2:
The number 747 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 747

Advancing to step 3:
747 goes into 686 0 times with a remainder of 686.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 686, we end up with 686.
Append the next digit (3) from the dividend to 686 and continue with: 6863 / 747

Going ahead to step 4:
If we divide 6863 by 747, we get 9 and a remainder of 140.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 6723 from 6863 and we're left with 140.
Fetch the next digit (8) from the dividend, attach it to 140 and continue: 1408 / 747

Let's proceed to step 5:
1408 divided by 747 is 1 with a remainder of 661.
The next digit of our result is 1. 
Result so far: 91.0
Subtract 747 from 1408 to get 661.
Append the next digit (7) from the dividend to 661 and continue with: 6617 / 747

Advancing to step 6:
When dividing 6617 by 747, we get 8 with a remainder of 641.
The number 8 becomes the next digit in our result. 
Result so far: 918.0
Subtract 5976 from 6617 to get 641.
Append the next digit (1) from the dividend to 641 and continue with: 6411 / 747

Advancing to step 7:
If we divide 6411 by 747, we get 8 and a remainder of 435.
Record the quotient 8 as the next digit in the result. 
Result so far: 9188.0
Subtracting 5976 from 6411 leaves us with 435.
Bring next digit (0) of the dividend behind the 435 and repeat the process: 4350 / 747

Let's proceed to step 8:
The number 747 fits into 4350 5 times, leaving a remainder of 615.
Put 5 as the next digit of the answer. 
Result so far: 91885.0
If we subtract 3735 from 4350, we get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 9:
The number 747 fits into 6150 8 times, leaving a remainder of 174.
The next digit of our result is 8. 
Result so far: 91885.8
If we take 5976 away from 6150, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 10:
747 goes into 1740 2 times with a remainder of 246.
The number 2 becomes the next digit in our result. 
Result so far: 91885.82
Subtracting 1494 from 1740 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 11:
747 can be fit into 2460 3 times, resulting in a remainder of 219.
The number 3 becomes the next digit in our result. 
Result so far: 91885.823
The remainder is 219 after subtracting 2241 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 12:
2190 divided by 747 is 2 with a remainder of 696.
Record the quotient 2 as the next digit in the result. 
Result so far: 91885.8232
The remainder is 696 after subtracting 1494 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Step 13:
If we divide 6960 by 747, we get 9 and a remainder of 237.
Write down 9 as next digit of the result. 
Result so far: 91885.82329
Subtract 6723 from 6960 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 14:
2370 divided by 747 is 3 with a remainder of 129.
Record the quotient 3 as the next digit in the result. 
Result so far: 91885.823293
Subtracting 2241 from 2370 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 15:
747 goes into 1290 1 times with a remainder of 543.
Write down 1 as next digit of the result. 
Result so far: 91885.8232931
Subtracting 747 from 1290 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 16:
747 goes into 5430 7 times with a remainder of 201.
The next digit of our result is 7. 
Result so far: 91885.82329317
If we take 5229 away from 5430, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The final outcome is 91885.82329317, with a leftover of 2.01e-07.
