We're dividing 439555 by 57 
The aim is to understand the frequency of 57 in 439555.

On to step 1:
The number 57 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 57

Let's proceed to step 2:
43 divided by 57 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 57

Let's proceed to step 3:
When dividing 439 by 57, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 399 from 439 and we're left with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 57

Let's proceed to step 4:
57 goes into 405 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we subtract 399 from 405, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 57

On to step 5:
57 goes into 65 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 771.0
Deduct 57 from 65 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 57

On to step 6:
When dividing 85 by 57, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 7711.0
If we take 57 away from 85, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
57 can be fit into 280 4 times, resulting in a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 7711.4
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
57 can be fit into 520 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 7711.49
The remainder is 7 after subtracting 513 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
The number 57 fits into 70 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 7711.491
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
When dividing 130 by 57, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 7711.4912
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
When dividing 160 by 57, we get 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 7711.49122
If we take 114 away from 160, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 7711.49122 and a remainder of 4.6e-05.
