We're dividing 64373798 by 800 
We're looking to find how many times 800 goes into 64373798.

Moving on to step 1:
6 divided by 800 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 800

Going ahead to step 2:
If we divide 64 by 800, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 800

Let's proceed to step 3:
643 divided by 800 is 0 with a remainder of 643.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 643 to get 643.
Include the next digit (7) from the dividend after 643, then repeat: 6437 / 800

Moving on to step 4:
When dividing 6437 by 800, we get 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 6400 from 6437 to get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 800

On to step 5:
373 divided by 800 is 0 with a remainder of 373.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we subtract 0 from 373, we get 373.
Bring next digit (7) of the dividend behind the 373 and repeat the process: 3737 / 800

Advancing to step 6:
The number 800 fits into 3737 4 times, leaving a remainder of 537.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.0
Subtract 3200 from 3737 to get 537.
Include the next digit (9) from the dividend after 537, then repeat: 5379 / 800

Step 7:
800 can be fit into 5379 6 times, resulting in a remainder of 579.
Record the quotient 6 as the next digit in the result. 
Result so far: 8046.0
Subtract 4800 from 5379 to get 579.
Append the next digit (8) from the dividend to 579 and continue with: 5798 / 800

Let's proceed to step 8:
5798 divided by 800 is 7 with a remainder of 198.
Record the quotient 7 as the next digit in the result. 
Result so far: 80467.0
Subtracting 5600 from 5798 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 9:
800 can be fit into 1980 2 times, resulting in a remainder of 380.
Write down 2 as next digit of the result. 
Result so far: 80467.2
Subtract 1600 from 1980 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
If we divide 3800 by 800, we get 4 and a remainder of 600.
Write down 4 as next digit of the result. 
Result so far: 80467.24
Subtracting 3200 from 3800 leaves us 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.

Advancing to step 11:
If we divide 6000 by 800, we get 7 and a remainder of 400.
Put 7 as the next digit of the answer. 
Result so far: 80467.247
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:
The number 800 fits into 4000 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 80467.2475
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 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 80467.2475
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.

Step 14:
800 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80467.2475
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.

The final outcome is 80467.2475, with a leftover of 0.0.
