We divide 12039173 by 457
We want to divide 12039173 by 457.

On to step 1:
When dividing 1 by 457, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 457

Advancing to step 2:
457 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 457

Step 3:
457 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 120, we end up with 120.
Grab the next digit (3) from the dividend, add it to 120, then carry on: 1203 / 457

Advancing to step 4:
If we divide 1203 by 457, we get 2 and a remainder of 289.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 289 after subtracting 914 from 1203.
Take the next digit (9) from the dividend and append it to 289, then repeat: 2899 / 457

Moving on to step 5:
The number 457 fits into 2899 6 times, leaving a remainder of 157.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 2742 from 2899, we get 157.
Take the next digit (1) from the dividend and append it to 157, then repeat: 1571 / 457

Advancing to step 6:
If we divide 1571 by 457, we get 3 and a remainder of 200.
Put 3 as the next digit of the answer. 
Result so far: 263.0
Deduct 1371 from 1571 and we're left with 200.
Append the next digit (7) from the dividend to 200 and continue with: 2007 / 457

Step 7:
457 can be fit into 2007 4 times, resulting in a remainder of 179.
Write down 4 as next digit of the result. 
Result so far: 2634.0
If we subtract 1828 from 2007, we get 179.
Grab the next digit (3) from the dividend, add it to 179, then carry on: 1793 / 457

Going ahead to step 8:
1793 divided by 457 is 3 with a remainder of 422.
The next digit of our result is 3. 
Result so far: 26343.0
If we take 1371 away from 1793, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 9:
If we divide 4220 by 457, we get 9 and a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 26343.9
Subtract 4113 from 4220 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 10:
457 can be fit into 1070 2 times, resulting in a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 26343.92
If we take 914 away from 1070, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 11:
1560 divided by 457 is 3 with a remainder of 189.
Write down 3 as next digit of the result. 
Result so far: 26343.923
The remainder is 189 after subtracting 1371 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 12:
The number 457 fits into 1890 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 26343.9234
Subtracting 1828 from 1890 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
457 can be fit into 620 1 times, resulting in a remainder of 163.
The number 1 becomes the next digit in our result. 
Result so far: 26343.92341
If we subtract 457 from 620, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 14:
If we divide 1630 by 457, we get 3 and a remainder of 259.
Use 3 as the next digit of our solution. 
Result so far: 26343.923413
If we subtract 1371 from 1630, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 15:
The number 457 fits into 2590 5 times, leaving a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 26343.9234135
Subtract 2285 from 2590 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 16:
3050 divided by 457 is 6 with a remainder of 308.
Write down 6 as next digit of the result. 
Result so far: 26343.92341356
Subtracting 2742 from 3050 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The final result is 26343.92341356 with a remainder of 3.08e-07.
