39109470 ÷ 808 
We want to divide 39109470 by 808.

Advancing to step 1:
The number 808 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
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 808

On to step 2:
The number 808 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 808

Going ahead to step 3:
808 goes into 391 0 times with a remainder of 391.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 391 to get 391.
Include the next digit (0) from the dividend after 391, then repeat: 3910 / 808

Step 4:
The number 808 fits into 3910 4 times, leaving a remainder of 678.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3232 from 3910 and we're left with 678.
Bring next digit (9) of the dividend behind the 678 and repeat the process: 6789 / 808

Moving on to step 5:
808 can be fit into 6789 8 times, resulting in a remainder of 325.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 6464 from 6789 and we're left with 325.
Fetch the next digit (4) from the dividend, attach it to 325 and continue: 3254 / 808

Moving on to step 6:
The number 808 fits into 3254 4 times, leaving a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
The remainder is 22 after subtracting 3232 from 3254.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 808

On to step 7:
When dividing 227 by 808, we get 0 with a remainder of 227.
The next digit of our result is 0. 
Result so far: 4840.0
If we subtract 0 from 227, we get 227.
Grab the next digit (0) from the dividend, add it to 227, then carry on: 2270 / 808

Moving on to step 8:
If we divide 2270 by 808, we get 2 and a remainder of 654.
The number 2 becomes the next digit in our result. 
Result so far: 48402.0
Deduct 1616 from 2270 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Step 9:
6540 divided by 808 is 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 48402.8
If we subtract 6464 from 6540, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
808 goes into 760 0 times with a remainder of 760.
Put 0 as the next digit of the answer. 
Result so far: 48402.8
Subtract 0 from 760 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 11:
808 can be fit into 7600 9 times, resulting in a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 48402.809
If we take 7272 away from 7600, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
808 goes into 3280 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 48402.8094
The remainder is 48 after subtracting 3232 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
When dividing 480 by 808, we get 0 with a remainder of 480.
The next digit of our result is 0. 
Result so far: 48402.8094
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
4800 divided by 808 is 5 with a remainder of 760.
The next digit of our result is 5. 
Result so far: 48402.809405
If we take 4040 away from 4800, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 15:
808 goes into 7600 9 times with a remainder of 328.
Write down 9 as next digit of the result. 
Result so far: 48402.8094059
Deduct 7272 from 7600 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 16:
3280 divided by 808 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 48402.80940594
Subtract 3232 from 3280 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 48402.80940594 and a remainder of 4.8e-08.
