We look at the division of 63037017 by 538 
The aim is to understand the frequency of 538 in 63037017.

On to step 1:
6 divided by 538 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 538

Going ahead to step 2:
If we divide 63 by 538, we get 0 and a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 538

Going ahead to step 3:
538 goes into 630 1 times with a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 92 after subtracting 538 from 630.
Include the next digit (3) from the dividend after 92, then repeat: 923 / 538

On to step 4:
538 can be fit into 923 1 times, resulting in a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 538 from 923 and we're left with 385.
Grab the next digit (7) from the dividend, add it to 385, then carry on: 3857 / 538

On to step 5:
538 can be fit into 3857 7 times, resulting in a remainder of 91.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtracting 3766 from 3857 leaves us with 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 538

Going ahead to step 6:
910 divided by 538 is 1 with a remainder of 372.
Use 1 as the next digit of our solution. 
Result so far: 1171.0
The remainder is 372 after subtracting 538 from 910.
Grab the next digit (1) from the dividend, add it to 372, then carry on: 3721 / 538

On to step 7:
When dividing 3721 by 538, we get 6 with a remainder of 493.
The next digit of our result is 6. 
Result so far: 11716.0
Deduct 3228 from 3721 and we're left with 493.
Grab the next digit (7) from the dividend, add it to 493, then carry on: 4937 / 538

Going ahead to step 8:
538 can be fit into 4937 9 times, resulting in a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 117169.0
Subtracting 4842 from 4937 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 9:
If we divide 950 by 538, we get 1 and a remainder of 412.
The next digit of our result is 1. 
Result so far: 117169.1
If we subtract 538 from 950, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 10:
When dividing 4120 by 538, we get 7 with a remainder of 354.
The number 7 becomes the next digit in our result. 
Result so far: 117169.17
Subtracting 3766 from 4120 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 11:
If we divide 3540 by 538, we get 6 and a remainder of 312.
The next digit of our result is 6. 
Result so far: 117169.176
If we take 3228 away from 3540, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 12:
When dividing 3120 by 538, we get 5 with a remainder of 430.
The next digit of our result is 5. 
Result so far: 117169.1765
Deduct 2690 from 3120 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 13:
4300 divided by 538 is 7 with a remainder of 534.
Write down 7 as next digit of the result. 
Result so far: 117169.17657
Subtracting 3766 from 4300 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 14:
5340 divided by 538 is 9 with a remainder of 498.
Use 9 as the next digit of our solution. 
Result so far: 117169.176579
Deduct 4842 from 5340 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 15:
538 can be fit into 4980 9 times, resulting in a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 117169.1765799
Subtract 4842 from 4980 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 117169.1765799 with a remainder of 1.38e-06.
