We're dividing 610641 by 72 
The aim is to understand the frequency of 72 in 610641.

Going ahead to step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 72

On to step 2:
If we divide 61 by 72, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 72

Step 3:
610 divided by 72 is 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 576 away from 610, we end up with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 72

On to step 4:
346 divided by 72 is 4 with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 288 from 346, we get 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 72

Let's proceed to step 5:
The number 72 fits into 584 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 848.0
If we take 576 away from 584, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 72

Advancing to step 6:
72 can be fit into 81 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 8481.0
If we subtract 72 from 81, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 72, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 8481.1
If we subtract 72 from 90, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 72, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 8481.12
Subtract 144 from 180 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 8481.125
Deduct 360 from 360 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 72 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8481.125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8481.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 8481.125 with a remaining 0.0.
