153903 divided by 57 
We're looking to find how many times 57 goes into 153903.

Going ahead to step 1:
The number 57 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 57

Advancing to step 2:
If we divide 15 by 57, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 57

Advancing to step 3:
When dividing 153 by 57, we get 2 with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 39 after subtracting 114 from 153.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 57

Step 4:
57 can be fit into 399 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 399 from 399 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 57

Let's proceed to step 5:
When dividing 0 by 57, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 270.0
If we take 0 away from 0, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 57

On to step 6:
If we divide 3 by 57, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 2700.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
57 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2700.0
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.

Going ahead to step 8:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2700.05
Subtract 285 from 300 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
57 can be fit into 150 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 2700.052
If we take 114 away from 150, we end up 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.

On to step 10:
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: 2700.0526
Deduct 342 from 360 and we're left 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.

Step 11:
The number 57 fits into 180 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 2700.05263
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
If we divide 90 by 57, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 2700.052631
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.

Advancing to step 13:
330 divided by 57 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 2700.0526315
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.

Step 14:
The number 57 fits into 450 7 times, leaving a remainder of 51.
The next digit of our result is 7. 
Result so far: 2700.05263157
Deduct 399 from 450 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 2700.05263157 and a remainder of 5.1e-08.
