The number 813 fits into 1257 1 times, leaving a remainder of 444.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 813 from 1257 and we're left with 444.
Include the next digit (5) from the dividend after 444, then repeat: 4445 / 813

On to step 5:
If we divide 4445 by 813, we get 5 and a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 4065 from 4445 and we're left with 380.
Append the next digit (3) from the dividend to 380 and continue with: 3803 / 813

Going ahead to step 6:
813 goes into 3803 4 times with a remainder of 551.
Put 4 as the next digit of the answer. 
Result so far: 154.0
If we subtract 3252 from 3803, we get 551.
Grab the next digit (7) from the dividend, add it to 551, then carry on: 5517 / 813

On to step 7:
The number 813 fits into 5517 6 times, leaving a remainder of 639.
Write down 6 as next digit of the result. 
Result so far: 1546.0
If we take 4878 away from 5517, we end up with 639.
Include the next digit (3) from the dividend after 639, then repeat: 6393 / 813

Let's proceed to step 8:
813 can be fit into 6393 7 times, resulting in a remainder of 702.
Write down 7 as next digit of the result. 
Result so far: 15467.0
Subtracting 5691 from 6393 leaves us with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Going ahead to step 9:
813 can be fit into 7020 8 times, resulting in a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 15467.8
The remainder is 516 after subtracting 6504 from 7020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 10:
813 goes into 5160 6 times with a remainder of 282.
The number 6 becomes the next digit in our result. 
Result so far: 15467.86
Deduct 4878 from 5160 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 11:
If we divide 2820 by 813, we get 3 and a remainder of 381.
Write down 3 as next digit of the result. 
Result so far: 15467.863
The remainder is 381 after subtracting 2439 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 12:
813 goes into 3810 4 times with a remainder of 558.
Write down 4 as next digit of the result. 
Result so far: 15467.8634
If we take 3252 away from 3810, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 13:
813 goes into 5580 6 times with a remainder of 702.
The next digit of our result is 6. 
Result so far: 15467.86346
If we subtract 4878 from 5580, we get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Advancing to step 14:
813 goes into 7020 8 times with a remainder of 516.
The next digit of our result is 8. 
Result so far: 15467.863468
Subtracting 6504 from 7020 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 15:
If we divide 5160 by 813, we get 6 and a remainder of 282.
Write down 6 as next digit of the result. 
Result so far: 15467.8634686
Subtract 4878 from 5160 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 16:
If we divide 2820 by 813, we get 3 and a remainder of 381.
Record the quotient 3 as the next digit in the result. 
Result so far: 15467.86346863
If we subtract 2439 from 2820, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

After the division, we end up with 15467.86346863 and a remainder of 3.81e-07.
