We're dividing 39107531 by 447 
We want to divide 39107531 by 447.

Moving on to step 1:
The number 447 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 447

Advancing to step 2:
447 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 447

Step 3:
If we divide 391 by 447, we get 0 and a remainder of 391.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 391 and we're left with 391.
Grab the next digit (0) from the dividend, add it to 391, then carry on: 3910 / 447

On to step 4:
When dividing 3910 by 447, we get 8 with a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 3576 away from 3910, we end up with 334.
Append the next digit (7) from the dividend to 334 and continue with: 3347 / 447

Going ahead to step 5:
When dividing 3347 by 447, we get 7 with a remainder of 218.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 3129 from 3347 to get 218.
Take the next digit (5) from the dividend and append it to 218, then repeat: 2185 / 447

Going ahead to step 6:
The number 447 fits into 2185 4 times, leaving a remainder of 397.
The number 4 becomes the next digit in our result. 
Result so far: 874.0
Deduct 1788 from 2185 and we're left with 397.
Include the next digit (3) from the dividend after 397, then repeat: 3973 / 447

Advancing to step 7:
3973 divided by 447 is 8 with a remainder of 397.
The number 8 becomes the next digit in our result. 
Result so far: 8748.0
The remainder is 397 after subtracting 3576 from 3973.
Grab the next digit (1) from the dividend, add it to 397, then carry on: 3971 / 447

Advancing to step 8:
447 goes into 3971 8 times with a remainder of 395.
The number 8 becomes the next digit in our result. 
Result so far: 87488.0
Subtracting 3576 from 3971 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 9:
The number 447 fits into 3950 8 times, leaving a remainder of 374.
Put 8 as the next digit of the answer. 
Result so far: 87488.8
Subtract 3576 from 3950 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 10:
If we divide 3740 by 447, we get 8 and a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 87488.88
If we take 3576 away from 3740, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The quotient of the division is 87488.88, and the remainder is 0.164.
