40859880 divided by 393 
We want to divide 40859880 by 393.

Going ahead to step 1:
393 goes into 4 0 times with 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.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 393

On to step 2:
40 divided by 393 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 393

Moving on to step 3:
393 goes into 408 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 393 from 408, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 393

Going ahead to step 4:
155 divided by 393 is 0 with a remainder of 155.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 155 after subtracting 0 from 155.
Grab the next digit (9) from the dividend, add it to 155, then carry on: 1559 / 393

Advancing to step 5:
393 goes into 1559 3 times with a remainder of 380.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 1179 from 1559 to get 380.
Grab the next digit (8) from the dividend, add it to 380, then carry on: 3808 / 393

Let's proceed to step 6:
3808 divided by 393 is 9 with a remainder of 271.
The number 9 becomes the next digit in our result. 
Result so far: 1039.0
If we subtract 3537 from 3808, we get 271.
Fetch the next digit (8) from the dividend, attach it to 271 and continue: 2718 / 393

Going ahead to step 7:
If we divide 2718 by 393, we get 6 and a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 10396.0
The remainder is 360 after subtracting 2358 from 2718.
Bring next digit (0) of the dividend behind the 360 and repeat the process: 3600 / 393

Let's proceed to step 8:
The number 393 fits into 3600 9 times, leaving a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 103969.0
If we subtract 3537 from 3600, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
When dividing 630 by 393, we get 1 with a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 103969.1
Deduct 393 from 630 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 10:
393 can be fit into 2370 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 103969.16
Subtracting 2358 from 2370 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
The number 393 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 103969.16
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
When dividing 1200 by 393, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 103969.1603
The remainder is 21 after subtracting 1179 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
393 can be fit into 210 0 times, resulting in a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 103969.1603
Deduct 0 from 210 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 14:
393 goes into 2100 5 times with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 103969.160305
Subtracting 1965 from 2100 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 15:
393 goes into 1350 3 times with a remainder of 171.
Use 3 as the next digit of our solution. 
Result so far: 103969.1603053
If we subtract 1179 from 1350, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 16:
When dividing 1710 by 393, we get 4 with a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 103969.16030534
If we take 1572 away from 1710, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The quotient of the division is 103969.16030534, and the remainder is 1.38e-07.
