Let's divide 138357 by 57
We're looking to find how many times 57 goes into 138357.

On to step 1:
57 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 57

On to step 2:
13 divided by 57 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 57

Step 3:
138 divided by 57 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 114 from 138 and we're left with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 57

Step 4:
The number 57 fits into 243 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 15 after subtracting 228 from 243.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 57

Moving on to step 5:
The number 57 fits into 155 2 times, leaving a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 242.0
The remainder is 41 after subtracting 114 from 155.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 57

Let's proceed to step 6:
If we divide 417 by 57, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 2427.0
The remainder is 18 after subtracting 399 from 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 57 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 2427.3
If we subtract 171 from 180, we 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.

Moving on to step 8:
When dividing 90 by 57, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 2427.31
If we subtract 57 from 90, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
The number 57 fits into 330 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 2427.315
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.

On to step 10:
The number 57 fits into 450 7 times, leaving a remainder of 51.
The next digit of our result is 7. 
Result so far: 2427.3157
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 11:
510 divided by 57 is 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 2427.31578
Subtracting 456 from 510 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
If we divide 540 by 57, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 2427.315789
Subtracting 513 from 540 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
57 goes into 270 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 2427.3157894
Subtracting 228 from 270 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
If we divide 420 by 57, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 2427.31578947
If we subtract 399 from 420, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 2427.31578947, with a leftover of 2.1e-08.
