We look at the division of 218715 by 57 
We want to figure out the number of times 218715 can be divided by 57.

On to step 1:
57 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 57

Step 2:
57 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our 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

On to step 3:
If we divide 218 by 57, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 171 from 218, we get 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 57

Advancing to step 4:
477 divided by 57 is 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 456 from 477 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 57

Step 5:
211 divided by 57 is 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 383.0
Subtract 171 from 211 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 57

Advancing to step 6:
When dividing 405 by 57, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 3837.0
Deduct 399 from 405 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 57 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 3837.1
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
If we divide 30 by 57, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 3837.1
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 57 fits into 300 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3837.105
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
If we divide 150 by 57, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3837.1052
Deduct 114 from 150 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
The number 57 fits into 360 6 times, leaving a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 3837.10526
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
If we divide 180 by 57, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 3837.105263
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
The number 57 fits into 90 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 3837.1052631
Subtracting 57 from 90 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
330 divided by 57 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 3837.10526315
Subtract 285 from 330 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 3837.10526315 and a remainder of 4.5e-08.
