We're dividing 63743919 by 724 
The aim is to understand the frequency of 724 in 63743919.

Step 1:
When dividing 6 by 724, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 724

Going ahead to step 2:
The number 724 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 724

On to step 3:
724 goes into 637 0 times with a remainder of 637.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 637 to get 637.
Fetch the next digit (4) from the dividend, attach it to 637 and continue: 6374 / 724

Advancing to step 4:
When dividing 6374 by 724, we get 8 with a remainder of 582.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 582 after subtracting 5792 from 6374.
Take the next digit (3) from the dividend and append it to 582, then repeat: 5823 / 724

Moving on to step 5:
724 goes into 5823 8 times with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtracting 5792 from 5823 leaves us with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 724

Step 6:
724 can be fit into 319 0 times, resulting in a remainder of 319.
Use 0 as the next digit of our solution. 
Result so far: 880.0
Deduct 0 from 319 and we're left with 319.
Grab the next digit (1) from the dividend, add it to 319, then carry on: 3191 / 724

Advancing to step 7:
When dividing 3191 by 724, we get 4 with a remainder of 295.
The number 4 becomes the next digit in our result. 
Result so far: 8804.0
The remainder is 295 after subtracting 2896 from 3191.
Bring next digit (9) of the dividend behind the 295 and repeat the process: 2959 / 724

Let's proceed to step 8:
724 goes into 2959 4 times with a remainder of 63.
The next digit of our result is 4. 
Result so far: 88044.0
If we take 2896 away from 2959, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
724 can be fit into 630 0 times, resulting in a remainder of 630.
Write down 0 as next digit of the result. 
Result so far: 88044.0
Subtracting 0 from 630 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 10:
The number 724 fits into 6300 8 times, leaving a remainder of 508.
Put 8 as the next digit of the answer. 
Result so far: 88044.08
Subtract 5792 from 6300 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 11:
If we divide 5080 by 724, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 88044.087
The remainder is 12 after subtracting 5068 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
If we divide 120 by 724, we get 0 and a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 88044.087
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
If we divide 1200 by 724, we get 1 and a remainder of 476.
Write down 1 as next digit of the result. 
Result so far: 88044.08701
If we take 724 away from 1200, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 14:
724 goes into 4760 6 times with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 88044.087016
If we subtract 4344 from 4760, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 15:
If we divide 4160 by 724, we get 5 and a remainder of 540.
Record the quotient 5 as the next digit in the result. 
Result so far: 88044.0870165
Deduct 3620 from 4160 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 16:
When dividing 5400 by 724, we get 7 with a remainder of 332.
Put 7 as the next digit of the answer. 
Result so far: 88044.08701657
Subtract 5068 from 5400 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final result is 88044.08701657 with a remainder of 3.32e-07.
