Let's divide 7803 by 57
We want to divide 7803 by 57.

Let's proceed to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 57

Let's proceed to step 2:
78 divided by 57 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 57 away from 78, we end up with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 57

Going ahead to step 3:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 171 away from 210, we end up with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 57

Moving on to step 4:
When dividing 393 by 57, we get 6 with a remainder of 51.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 342 from 393 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.

Moving on to step 5:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 136.8
Deduct 456 from 510 and we're left 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.

Going ahead to step 6:
57 goes into 540 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 136.89
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.

Moving on to step 7:
When dividing 270 by 57, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 136.894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
The number 57 fits into 420 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 136.8947
Deduct 399 from 420 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
When dividing 210 by 57, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 136.89473
Subtracting 171 from 210 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 10:
The number 57 fits into 390 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 136.894736
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
The number 57 fits into 480 8 times, leaving a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 136.8947368
If we take 456 away from 480, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
If we divide 240 by 57, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 136.89473684
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 136.89473684, with a leftover of 1.2e-08.
