Grab the next digit (5) from the dividend, add it to 124, then carry on: 1245 / 791

On to step 4:
If we divide 1245 by 791, we get 1 and a remainder of 454.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 454 after subtracting 791 from 1245.
Take the next digit (7) from the dividend and append it to 454, then repeat: 4547 / 791

Let's proceed to step 5:
The number 791 fits into 4547 5 times, leaving a remainder of 592.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 592 after subtracting 3955 from 4547.
Append the next digit (6) from the dividend to 592 and continue with: 5926 / 791

On to step 6:
791 goes into 5926 7 times with a remainder of 389.
Put 7 as the next digit of the answer. 
Result so far: 157.0
The remainder is 389 after subtracting 5537 from 5926.
Include the next digit (0) from the dividend after 389, then repeat: 3890 / 791

Moving on to step 7:
If we divide 3890 by 791, we get 4 and a remainder of 726.
Put 4 as the next digit of the answer. 
Result so far: 1574.0
Subtracting 3164 from 3890 leaves us with 726.
Take the next digit (7) from the dividend and append it to 726, then repeat: 7267 / 791

Moving on to step 8:
The number 791 fits into 7267 9 times, leaving a remainder of 148.
Record the quotient 9 as the next digit in the result. 
Result so far: 15749.0
Subtract 7119 from 7267 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
The number 791 fits into 1480 1 times, leaving a remainder of 689.
The number 1 becomes the next digit in our result. 
Result so far: 15749.1
If we take 791 away from 1480, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Let's proceed to step 10:
The number 791 fits into 6890 8 times, leaving a remainder of 562.
Record the quotient 8 as the next digit in the result. 
Result so far: 15749.18
The remainder is 562 after subtracting 6328 from 6890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Advancing to step 11:
When dividing 5620 by 791, we get 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 15749.187
Deduct 5537 from 5620 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 12:
When dividing 830 by 791, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 15749.1871
Subtract 791 from 830 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
The number 791 fits into 390 0 times, leaving a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 15749.1871
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 14:
If we divide 3900 by 791, we get 4 and a remainder of 736.
The number 4 becomes the next digit in our result. 
Result so far: 15749.187104
The remainder is 736 after subtracting 3164 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 15:
When dividing 7360 by 791, we get 9 with a remainder of 241.
Use 9 as the next digit of our solution. 
Result so far: 15749.1871049
Subtract 7119 from 7360 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 16:
The number 791 fits into 2410 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 15749.18710493
If we subtract 2373 from 2410, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 15749.18710493 with a remaining 3.7e-08.
