72816550 divided by 597 
The aim is to understand the frequency of 597 in 72816550.

On to step 1:
597 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 597

Moving on to step 2:
The number 597 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 597

On to step 3:
If we divide 728 by 597, we get 1 and a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 131 after subtracting 597 from 728.
Grab the next digit (1) from the dividend, add it to 131, then carry on: 1311 / 597

Let's proceed to step 4:
If we divide 1311 by 597, we get 2 and a remainder of 117.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1194 from 1311 to get 117.
Grab the next digit (6) from the dividend, add it to 117, then carry on: 1176 / 597

Advancing to step 5:
597 can be fit into 1176 1 times, resulting in a remainder of 579.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtract 597 from 1176 to get 579.
Fetch the next digit (5) from the dividend, attach it to 579 and continue: 5795 / 597

Advancing to step 6:
5795 divided by 597 is 9 with a remainder of 422.
Record the quotient 9 as the next digit in the result. 
Result so far: 1219.0
Deduct 5373 from 5795 and we're left with 422.
Fetch the next digit (5) from the dividend, attach it to 422 and continue: 4225 / 597

Advancing to step 7:
597 can be fit into 4225 7 times, resulting in a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 12197.0
Deduct 4179 from 4225 and we're left with 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 597

Going ahead to step 8:
597 can be fit into 460 0 times, resulting in a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 121970.0
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 9:
597 can be fit into 4600 7 times, resulting in a remainder of 421.
Use 7 as the next digit of our solution. 
Result so far: 121970.7
If we take 4179 away from 4600, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

On to step 10:
4210 divided by 597 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 121970.77
If we subtract 4179 from 4210, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 121970.77 with a remainder of 0.031.
