We look at the division of 21842945 by 57 
We want to figure out the number of times 21842945 can be divided by 57.

On to step 1:
2 divided by 57 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 57

Step 2:
If we divide 21 by 57, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 57

Let's proceed to step 3:
When dividing 218 by 57, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 171 from 218 to get 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 57

Moving on to step 4:
57 goes into 474 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 456 from 474, we get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 57

Advancing to step 5:
If we divide 182 by 57, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 383.0
If we subtract 171 from 182, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 57

Advancing to step 6:
57 can be fit into 119 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 3832.0
Subtract 114 from 119 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 57

Going ahead to step 7:
The number 57 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 38320.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 57

Step 8:
If we divide 545 by 57, we get 9 and a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 383209.0
Deduct 513 from 545 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 57 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 383209.5
Subtracting 285 from 320 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
The number 57 fits into 350 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 383209.56
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 57, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 383209.561
The remainder is 23 after subtracting 57 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
57 goes into 230 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 383209.5614
If we take 228 away from 230, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
57 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 383209.5614
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
The number 57 fits into 200 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 383209.561403
Deduct 171 from 200 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 15:
The number 57 fits into 290 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 383209.5614035
If we take 285 away from 290, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
50 divided by 57 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 383209.5614035
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 383209.5614035 with a remaining 5e-08.
