39903391 ÷ 880 
We're looking to find how many times 880 goes into 39903391.

Moving on to step 1:
3 divided by 880 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 880

On to step 2:
880 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 880

Step 3:
The number 880 fits into 399 0 times, leaving a remainder of 399.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Grab the next digit (0) from the dividend, add it to 399, then carry on: 3990 / 880

On to step 4:
If we divide 3990 by 880, we get 4 and a remainder of 470.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 470 after subtracting 3520 from 3990.
Take the next digit (3) from the dividend and append it to 470, then repeat: 4703 / 880

Let's proceed to step 5:
The number 880 fits into 4703 5 times, leaving a remainder of 303.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 4400 away from 4703, we end up with 303.
Include the next digit (3) from the dividend after 303, then repeat: 3033 / 880

Advancing to step 6:
When dividing 3033 by 880, we get 3 with a remainder of 393.
Put 3 as the next digit of the answer. 
Result so far: 453.0
Deduct 2640 from 3033 and we're left with 393.
Take the next digit (9) from the dividend and append it to 393, then repeat: 3939 / 880

On to step 7:
If we divide 3939 by 880, we get 4 and a remainder of 419.
Put 4 as the next digit of the answer. 
Result so far: 4534.0
Deduct 3520 from 3939 and we're left with 419.
Include the next digit (1) from the dividend after 419, then repeat: 4191 / 880

Going ahead to step 8:
When dividing 4191 by 880, we get 4 with a remainder of 671.
Write down 4 as next digit of the result. 
Result so far: 45344.0
The remainder is 671 after subtracting 3520 from 4191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Going ahead to step 9:
880 goes into 6710 7 times with a remainder of 550.
Write down 7 as next digit of the result. 
Result so far: 45344.7
Deduct 6160 from 6710 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 10:
If we divide 5500 by 880, we get 6 and a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 45344.76
The remainder is 220 after subtracting 5280 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
When dividing 2200 by 880, we get 2 with a remainder of 440.
Put 2 as the next digit of the answer. 
Result so far: 45344.762
The remainder is 440 after subtracting 1760 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 12:
The number 880 fits into 4400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45344.7625
If we subtract 4400 from 4400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
The number 880 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45344.7625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
The number 880 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45344.7625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 45344.7625 with a remaining 0.0.
