We divide 72071245 by 800
We're looking to find how many times 800 goes into 72071245.

Advancing to step 1:
If we divide 7 by 800, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 800

Advancing to step 2:
800 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 800

Going ahead to step 3:
800 goes into 720 0 times with a remainder of 720.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 720, we end up with 720.
Include the next digit (7) from the dividend after 720, then repeat: 7207 / 800

Advancing to step 4:
7207 divided by 800 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7200 from 7207 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 800

Going ahead to step 5:
800 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 71, we end up with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 800

Step 6:
The number 800 fits into 712 0 times, leaving a remainder of 712.
Record the quotient 0 as the next digit in the result. 
Result so far: 900.0
If we take 0 away from 712, we end up with 712.
Append the next digit (4) from the dividend to 712 and continue with: 7124 / 800

On to step 7:
When dividing 7124 by 800, we get 8 with a remainder of 724.
Put 8 as the next digit of the answer. 
Result so far: 9008.0
If we subtract 6400 from 7124, we get 724.
Grab the next digit (5) from the dividend, add it to 724, then carry on: 7245 / 800

On to step 8:
The number 800 fits into 7245 9 times, leaving a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 90089.0
Deduct 7200 from 7245 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
800 can be fit into 450 0 times, resulting in a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 90089.0
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
When dividing 4500 by 800, we get 5 with a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 90089.05
If we take 4000 away from 4500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
The number 800 fits into 5000 6 times, leaving a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 90089.056
If we take 4800 away from 5000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
If we divide 2000 by 800, we get 2 and a remainder of 400.
The next digit of our result is 2. 
Result so far: 90089.0562
The remainder is 400 after subtracting 1600 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
The number 800 fits into 4000 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 90089.05625
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.

Going ahead to step 14:
0 divided by 800 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 90089.05625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
0 divided by 800 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90089.05625
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.

After the division, we end up with 90089.05625 and a remainder of 0.0.
