We look at the division of 43910280 by 764 
The aim is to understand the frequency of 764 in 43910280.

On to step 1:
764 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 764

Advancing to step 2:
764 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 764

On to step 3:
When dividing 439 by 764, we get 0 with a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 439, we get 439.
Grab the next digit (1) from the dividend, add it to 439, then carry on: 4391 / 764

Step 4:
If we divide 4391 by 764, we get 5 and a remainder of 571.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 3820 from 4391 to get 571.
Bring next digit (0) of the dividend behind the 571 and repeat the process: 5710 / 764

Advancing to step 5:
When dividing 5710 by 764, we get 7 with a remainder of 362.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we subtract 5348 from 5710, we get 362.
Append the next digit (2) from the dividend to 362 and continue with: 3622 / 764

On to step 6:
When dividing 3622 by 764, we get 4 with a remainder of 566.
Put 4 as the next digit of the answer. 
Result so far: 574.0
If we take 3056 away from 3622, we end up with 566.
Take the next digit (8) from the dividend and append it to 566, then repeat: 5668 / 764

Advancing to step 7:
5668 divided by 764 is 7 with a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 5747.0
Deduct 5348 from 5668 and we're left with 320.
Fetch the next digit (0) from the dividend, attach it to 320 and continue: 3200 / 764

Advancing to step 8:
3200 divided by 764 is 4 with a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 57474.0
The remainder is 144 after subtracting 3056 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 9:
764 can be fit into 1440 1 times, resulting in a remainder of 676.
Write down 1 as next digit of the result. 
Result so far: 57474.1
If we take 764 away from 1440, we end up with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Moving on to step 10:
6760 divided by 764 is 8 with a remainder of 648.
Write down 8 as next digit of the result. 
Result so far: 57474.18
If we subtract 6112 from 6760, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 11:
764 goes into 6480 8 times with a remainder of 368.
The next digit of our result is 8. 
Result so far: 57474.188
Subtract 6112 from 6480 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The quotient of the division is 57474.188, and the remainder is 0.0368.
