We're dividing 121333 by 57 
The aim is to understand the frequency of 57 in 121333.

On to step 1:
The number 57 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 57

Moving on to step 2:
The number 57 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 57

On to step 3:
The number 57 fits into 121 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 114 away from 121, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 57

On to step 4:
The number 57 fits into 73 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 57 from 73 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 57

Step 5:
If we divide 163 by 57, we get 2 and a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 212.0
If we subtract 114 from 163, we get 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 57

Advancing to step 6:
493 divided by 57 is 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 2128.0
Subtracting 456 from 493 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
57 goes into 370 6 times with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 2128.6
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
280 divided by 57 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 2128.64
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
57 goes into 520 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 2128.649
Subtract 513 from 520 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
57 goes into 70 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 2128.6491
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
When dividing 130 by 57, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2128.64912
Subtract 114 from 130 to 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.

Step 12:
160 divided by 57 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 2128.649122
Subtract 114 from 160 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 2128.649122, with a leftover of 4.6e-06.
