We divide 7139415 by 800
We want to divide 7139415 by 800.

Going ahead to step 1:
800 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 800

Let's proceed to step 2:
The number 800 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 800

Moving on to step 3:
713 divided by 800 is 0 with a remainder of 713.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 713 leaves us with 713.
Grab the next digit (9) from the dividend, add it to 713, then carry on: 7139 / 800

Going ahead to step 4:
800 can be fit into 7139 8 times, resulting in a remainder of 739.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6400 from 7139 to get 739.
Grab the next digit (4) from the dividend, add it to 739, then carry on: 7394 / 800

Going ahead to step 5:
800 goes into 7394 9 times with a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Deduct 7200 from 7394 and we're left with 194.
Bring next digit (1) of the dividend behind the 194 and repeat the process: 1941 / 800

Step 6:
800 can be fit into 1941 2 times, resulting in a remainder of 341.
Put 2 as the next digit of the answer. 
Result so far: 892.0
The remainder is 341 after subtracting 1600 from 1941.
Include the next digit (5) from the dividend after 341, then repeat: 3415 / 800

On to step 7:
800 can be fit into 3415 4 times, resulting in a remainder of 215.
Record the quotient 4 as the next digit in the result. 
Result so far: 8924.0
Deduct 3200 from 3415 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 8:
The number 800 fits into 2150 2 times, leaving a remainder of 550.
Write down 2 as next digit of the result. 
Result so far: 8924.2
Subtracting 1600 from 2150 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 9:
The number 800 fits into 5500 6 times, leaving a remainder of 700.
Use 6 as the next digit of our solution. 
Result so far: 8924.26
If we subtract 4800 from 5500, we get 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 10:
800 goes into 7000 8 times with a remainder of 600.
Put 8 as the next digit of the answer. 
Result so far: 8924.268
If we take 6400 away from 7000, we end up 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.

On to step 11:
If we divide 6000 by 800, we get 7 and a remainder of 400.
The number 7 becomes the next digit in our result. 
Result so far: 8924.2687
If we subtract 5600 from 6000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
800 can be fit into 4000 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 8924.26875
The remainder is 0 after subtracting 4000 from 4000.
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 13:
800 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8924.26875
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.

Let's proceed to step 14:
800 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8924.26875
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 8924.26875 and a remainder of 0.0.
