We're dividing 39791121 by 724 
The aim is to understand the frequency of 724 in 39791121.

Let's proceed to step 1:
When dividing 3 by 724, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 724

Moving on to step 2:
724 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 724

Step 3:
The number 724 fits into 397 0 times, leaving a remainder of 397.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 397, we end up with 397.
Fetch the next digit (9) from the dividend, attach it to 397 and continue: 3979 / 724

On to step 4:
The number 724 fits into 3979 5 times, leaving a remainder of 359.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 359 after subtracting 3620 from 3979.
Take the next digit (1) from the dividend and append it to 359, then repeat: 3591 / 724

Moving on to step 5:
If we divide 3591 by 724, we get 4 and a remainder of 695.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we take 2896 away from 3591, we end up with 695.
Grab the next digit (1) from the dividend, add it to 695, then carry on: 6951 / 724

Step 6:
If we divide 6951 by 724, we get 9 and a remainder of 435.
Put 9 as the next digit of the answer. 
Result so far: 549.0
Subtract 6516 from 6951 to get 435.
Take the next digit (2) from the dividend and append it to 435, then repeat: 4352 / 724

Going ahead to step 7:
If we divide 4352 by 724, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 5496.0
Subtract 4344 from 4352 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 724

Let's proceed to step 8:
The number 724 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 54960.0
Deduct 0 from 81 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
810 divided by 724 is 1 with a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 54960.1
Deduct 724 from 810 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
When dividing 860 by 724, we get 1 with a remainder of 136.
Record the quotient 1 as the next digit in the result. 
Result so far: 54960.11
If we subtract 724 from 860, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 54960.11, with a leftover of 0.136.
