We look at the division of 8615414 by 743 
The aim is to understand the frequency of 743 in 8615414.

On to step 1:
743 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 743

Let's proceed to step 2:
The number 743 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 743

On to step 3:
743 can be fit into 861 1 times, resulting in a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 743 from 861 and we're left with 118.
Append the next digit (5) from the dividend to 118 and continue with: 1185 / 743

Step 4:
743 goes into 1185 1 times with a remainder of 442.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 743 from 1185 and we're left with 442.
Grab the next digit (4) from the dividend, add it to 442, then carry on: 4424 / 743

Step 5:
743 goes into 4424 5 times with a remainder of 709.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we subtract 3715 from 4424, we get 709.
Grab the next digit (1) from the dividend, add it to 709, then carry on: 7091 / 743

Moving on to step 6:
743 goes into 7091 9 times with a remainder of 404.
Write down 9 as next digit of the result. 
Result so far: 1159.0
If we subtract 6687 from 7091, we get 404.
Take the next digit (4) from the dividend and append it to 404, then repeat: 4044 / 743

Let's proceed to step 7:
The number 743 fits into 4044 5 times, leaving a remainder of 329.
Put 5 as the next digit of the answer. 
Result so far: 11595.0
If we subtract 3715 from 4044, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 8:
The number 743 fits into 3290 4 times, leaving a remainder of 318.
Write down 4 as next digit of the result. 
Result so far: 11595.4
The remainder is 318 after subtracting 2972 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 9:
If we divide 3180 by 743, we get 4 and a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 11595.44
If we take 2972 away from 3180, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 11595.44 with a remainder of 0.208.
