We're dividing 75887184 by 724 
The aim is to understand the frequency of 724 in 75887184.

Moving on to step 1:
The number 724 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 724

Advancing to step 2:
When dividing 75 by 724, we get 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 724

On to step 3:
758 divided by 724 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 724 from 758 to get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 724

Going ahead to step 4:
348 divided by 724 is 0 with a remainder of 348.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 348 after subtracting 0 from 348.
Fetch the next digit (7) from the dividend, attach it to 348 and continue: 3487 / 724

Advancing to step 5:
724 goes into 3487 4 times with a remainder of 591.
The next digit of our result is 4. 
Result so far: 104.0
The remainder is 591 after subtracting 2896 from 3487.
Grab the next digit (1) from the dividend, add it to 591, then carry on: 5911 / 724

Advancing to step 6:
724 goes into 5911 8 times with a remainder of 119.
Use 8 as the next digit of our solution. 
Result so far: 1048.0
Deduct 5792 from 5911 and we're left with 119.
Fetch the next digit (8) from the dividend, attach it to 119 and continue: 1198 / 724

On to step 7:
If we divide 1198 by 724, we get 1 and a remainder of 474.
Write down 1 as next digit of the result. 
Result so far: 10481.0
Subtract 724 from 1198 to get 474.
Take the next digit (4) from the dividend and append it to 474, then repeat: 4744 / 724

Advancing to step 8:
When dividing 4744 by 724, we get 6 with a remainder of 400.
Record the quotient 6 as the next digit in the result. 
Result so far: 104816.0
The remainder is 400 after subtracting 4344 from 4744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 9:
724 goes into 4000 5 times with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 104816.5
Subtracting 3620 from 4000 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
The number 724 fits into 3800 5 times, leaving a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 104816.55
If we take 3620 away from 3800, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 104816.55 and a remainder of 0.18.
