We're dividing 52101186 by 597 
The aim is to understand the frequency of 597 in 52101186.

On to step 1:
597 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 597

Moving on to step 2:
597 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 597

On to step 3:
When dividing 521 by 597, we get 0 with a remainder of 521.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 521 leaves us with 521.
Include the next digit (0) from the dividend after 521, then repeat: 5210 / 597

Advancing to step 4:
5210 divided by 597 is 8 with a remainder of 434.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 4776 from 5210, we get 434.
Fetch the next digit (1) from the dividend, attach it to 434 and continue: 4341 / 597

On to step 5:
When dividing 4341 by 597, we get 7 with a remainder of 162.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 4179 from 4341 to get 162.
Include the next digit (1) from the dividend after 162, then repeat: 1621 / 597

Going ahead to step 6:
When dividing 1621 by 597, we get 2 with a remainder of 427.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
The remainder is 427 after subtracting 1194 from 1621.
Append the next digit (8) from the dividend to 427 and continue with: 4278 / 597

Going ahead to step 7:
If we divide 4278 by 597, we get 7 and a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 8727.0
If we subtract 4179 from 4278, we get 99.
Bring next digit (6) of the dividend behind the 99 and repeat the process: 996 / 597

Advancing to step 8:
597 can be fit into 996 1 times, resulting in a remainder of 399.
The next digit of our result is 1. 
Result so far: 87271.0
If we take 597 away from 996, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 9:
The number 597 fits into 3990 6 times, leaving a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 87271.6
If we subtract 3582 from 3990, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 10:
597 goes into 4080 6 times with a remainder of 498.
Write down 6 as next digit of the result. 
Result so far: 87271.66
Subtract 3582 from 4080 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Our division results in 87271.66 with a remaining 0.498.
