Let's divide 3937897 by 880
Our goal is to divide 3937897 by 880.

Going ahead to step 1:
When dividing 3 by 880, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 880

Going ahead to step 2:
When dividing 39 by 880, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 880

Step 3:
880 can be fit into 393 0 times, resulting in a remainder of 393.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 393 after subtracting 0 from 393.
Include the next digit (7) from the dividend after 393, then repeat: 3937 / 880

Step 4:
The number 880 fits into 3937 4 times, leaving a remainder of 417.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3520 away from 3937, we end up with 417.
Bring next digit (8) of the dividend behind the 417 and repeat the process: 4178 / 880

Step 5:
880 goes into 4178 4 times with a remainder of 658.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 3520 from 4178 and we're left with 658.
Take the next digit (9) from the dividend and append it to 658, then repeat: 6589 / 880

Advancing to step 6:
6589 divided by 880 is 7 with a remainder of 429.
Record the quotient 7 as the next digit in the result. 
Result so far: 447.0
Deduct 6160 from 6589 and we're left with 429.
Bring next digit (7) of the dividend behind the 429 and repeat the process: 4297 / 880

Moving on to step 7:
If we divide 4297 by 880, we get 4 and a remainder of 777.
Record the quotient 4 as the next digit in the result. 
Result so far: 4474.0
The remainder is 777 after subtracting 3520 from 4297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Advancing to step 8:
The number 880 fits into 7770 8 times, leaving a remainder of 730.
Use 8 as the next digit of our solution. 
Result so far: 4474.8
Subtract 7040 from 7770 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 9:
880 can be fit into 7300 8 times, resulting in a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 4474.88
If we take 7040 away from 7300, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 4474.88 with a remaining 0.26.
