We're dividing 43869128 by 390 
Our goal is to divide 43869128 by 390.

Moving on to step 1:
390 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 390

On to step 2:
The number 390 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 390

Moving on to step 3:
When dividing 438 by 390, we get 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
If we take 390 away from 438, we end up with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 390

Moving on to step 4:
390 goes into 486 1 times with a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 390 from 486, we get 96.
Append the next digit (9) from the dividend to 96 and continue with: 969 / 390

Advancing to step 5:
When dividing 969 by 390, we get 2 with a remainder of 189.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Subtract 780 from 969 to get 189.
Bring next digit (1) of the dividend behind the 189 and repeat the process: 1891 / 390

Step 6:
If we divide 1891 by 390, we get 4 and a remainder of 331.
The next digit of our result is 4. 
Result so far: 1124.0
Subtract 1560 from 1891 to get 331.
Include the next digit (2) from the dividend after 331, then repeat: 3312 / 390

Going ahead to step 7:
390 goes into 3312 8 times with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 11248.0
Subtracting 3120 from 3312 leaves us with 192.
Include the next digit (8) from the dividend after 192, then repeat: 1928 / 390

Moving on to step 8:
1928 divided by 390 is 4 with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 112484.0
Subtracting 1560 from 1928 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 9:
If we divide 3680 by 390, we get 9 and a remainder of 170.
Write down 9 as next digit of the result. 
Result so far: 112484.9
Deduct 3510 from 3680 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
The number 390 fits into 1700 4 times, leaving a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 112484.94
Subtracting 1560 from 1700 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
1400 divided by 390 is 3 with a remainder of 230.
The number 3 becomes the next digit in our result. 
Result so far: 112484.943
Deduct 1170 from 1400 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 12:
When dividing 2300 by 390, we get 5 with a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 112484.9435
If we take 1950 away from 2300, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
390 can be fit into 3500 8 times, resulting in a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 112484.94358
If we subtract 3120 from 3500, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
390 can be fit into 3800 9 times, resulting in a remainder of 290.
Use 9 as the next digit of our solution. 
Result so far: 112484.943589
If we take 3510 away from 3800, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 15:
390 can be fit into 2900 7 times, resulting in a remainder of 170.
Use 7 as the next digit of our solution. 
Result so far: 112484.9435897
If we take 2730 away from 2900, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 16:
When dividing 1700 by 390, we get 4 with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 112484.94358974
If we take 1560 away from 1700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 112484.94358974 with a remaining 1.4e-07.
