We're dividing 100521 by 56 
The aim is to understand the frequency of 56 in 100521.

On to step 1:
56 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 56

Moving on to step 2:
The number 56 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 56

Going ahead to step 3:
56 goes into 100 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 56 away from 100, we end up with 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 56

Going ahead to step 4:
When dividing 445 by 56, we get 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 53 after subtracting 392 from 445.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 56

Going ahead to step 5:
532 divided by 56 is 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
Subtract 504 from 532 to get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 56

On to step 6:
56 goes into 281 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1795.0
Subtract 280 from 281 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 56 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 1795.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
56 goes into 100 1 times with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 1795.01
If we take 56 away from 100, 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.

On to step 9:
440 divided by 56 is 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 1795.017
Subtracting 392 from 440 leaves us 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.

Going ahead to step 10:
If we divide 480 by 56, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 1795.0178
If we subtract 448 from 480, 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.

Moving on to step 11:
When dividing 320 by 56, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1795.01785
Deduct 280 from 320 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.

Moving on to step 12:
56 goes into 400 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1795.017857
If we take 392 away from 400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
The number 56 fits into 80 1 times, leaving a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1795.0178571
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
The number 56 fits into 240 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1795.01785714
If we take 224 away from 240, we end up 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.

The final outcome is 1795.01785714, with a leftover of 1.6e-08.
