Advancing to step 5:
1879 divided by 389 is 4 with a remainder of 323.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 323 after subtracting 1556 from 1879.
Grab the next digit (8) from the dividend, add it to 323, then carry on: 3238 / 389

Going ahead to step 6:
The number 389 fits into 3238 8 times, leaving a remainder of 126.
The next digit of our result is 8. 
Result so far: 448.0
The remainder is 126 after subtracting 3112 from 3238.
Fetch the next digit (0) from the dividend, attach it to 126 and continue: 1260 / 389

Going ahead to step 7:
The number 389 fits into 1260 3 times, leaving a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 4483.0
If we take 1167 away from 1260, we end up with 93.
Take the next digit (6) from the dividend and append it to 93, then repeat: 936 / 389

Going ahead to step 8:
If we divide 936 by 389, we get 2 and a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 44832.0
If we subtract 778 from 936, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 9:
1580 divided by 389 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 44832.4
If we subtract 1556 from 1580, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
389 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 44832.4
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
389 goes into 2400 6 times with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 44832.406
The remainder is 66 after subtracting 2334 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
660 divided by 389 is 1 with a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 44832.4061
If we take 389 away from 660, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 13:
When dividing 2710 by 389, we get 6 with a remainder of 376.
The next digit of our result is 6. 
Result so far: 44832.40616
The remainder is 376 after subtracting 2334 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 14:
389 can be fit into 3760 9 times, resulting in a remainder of 259.
The next digit of our result is 9. 
Result so far: 44832.406169
The remainder is 259 after subtracting 3501 from 3760.
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:
If we divide 2590 by 389, we get 6 and a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 44832.4061696
If we take 2334 away from 2590, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 16:
389 can be fit into 2560 6 times, resulting in a remainder of 226.
Write down 6 as next digit of the result. 
Result so far: 44832.40616966
Subtract 2334 from 2560 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The quotient of the division is 44832.40616966, and the remainder is 2.26e-07.
