We're dividing 83510431 by 800 
We want to figure out the number of times 83510431 can be divided by 800.

Moving on to step 1:
When dividing 8 by 800, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 800

Step 2:
800 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 800

Step 3:
800 goes into 835 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 35 after subtracting 800 from 835.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 800

Let's proceed to step 4:
351 divided by 800 is 0 with a remainder of 351.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 351 leaves us with 351.
Append the next digit (0) from the dividend to 351 and continue with: 3510 / 800

Advancing to step 5:
If we divide 3510 by 800, we get 4 and a remainder of 310.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 310 after subtracting 3200 from 3510.
Take the next digit (4) from the dividend and append it to 310, then repeat: 3104 / 800

Step 6:
The number 800 fits into 3104 3 times, leaving a remainder of 704.
Write down 3 as next digit of the result. 
Result so far: 1043.0
If we subtract 2400 from 3104, we get 704.
Append the next digit (3) from the dividend to 704 and continue with: 7043 / 800

Advancing to step 7:
If we divide 7043 by 800, we get 8 and a remainder of 643.
The number 8 becomes the next digit in our result. 
Result so far: 10438.0
If we subtract 6400 from 7043, we get 643.
Include the next digit (1) from the dividend after 643, then repeat: 6431 / 800

Moving on to step 8:
If we divide 6431 by 800, we get 8 and a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 104388.0
Deduct 6400 from 6431 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
800 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 104388.0
If we subtract 0 from 310, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
3100 divided by 800 is 3 with a remainder of 700.
Write down 3 as next digit of the result. 
Result so far: 104388.03
If we take 2400 away from 3100, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
800 goes into 7000 8 times with a remainder of 600.
The next digit of our result is 8. 
Result so far: 104388.038
Deduct 6400 from 7000 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 12:
800 goes into 6000 7 times with a remainder of 400.
The next digit of our result is 7. 
Result so far: 104388.0387
If we take 5600 away from 6000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
If we divide 4000 by 800, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 104388.03875
Deduct 4000 from 4000 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.

Moving on to step 14:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 104388.03875
If we subtract 0 from 0, 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.

On to step 15:
The number 800 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 104388.03875
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.

The final result is 104388.03875 with a remainder of 0.0.
