42637542 divided by 800 
We're looking to find how many times 800 goes into 42637542.

Let's proceed to step 1:
800 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 800

Going ahead to step 2:
800 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 800

On to step 3:
When dividing 426 by 800, we get 0 with a remainder of 426.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 426 leaves us with 426.
Include the next digit (3) from the dividend after 426, then repeat: 4263 / 800

Moving on to step 4:
800 can be fit into 4263 5 times, resulting in a remainder of 263.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 263 after subtracting 4000 from 4263.
Fetch the next digit (7) from the dividend, attach it to 263 and continue: 2637 / 800

Step 5:
When dividing 2637 by 800, we get 3 with a remainder of 237.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 2400 from 2637 leaves us with 237.
Bring next digit (5) of the dividend behind the 237 and repeat the process: 2375 / 800

On to step 6:
800 goes into 2375 2 times with a remainder of 775.
Put 2 as the next digit of the answer. 
Result so far: 532.0
Subtract 1600 from 2375 to get 775.
Grab the next digit (4) from the dividend, add it to 775, then carry on: 7754 / 800

Let's proceed to step 7:
The number 800 fits into 7754 9 times, leaving a remainder of 554.
The next digit of our result is 9. 
Result so far: 5329.0
If we take 7200 away from 7754, we end up with 554.
Fetch the next digit (2) from the dividend, attach it to 554 and continue: 5542 / 800

Advancing to step 8:
800 goes into 5542 6 times with a remainder of 742.
Use 6 as the next digit of our solution. 
Result so far: 53296.0
Deduct 4800 from 5542 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 9:
If we divide 7420 by 800, we get 9 and a remainder of 220.
The number 9 becomes the next digit in our result. 
Result so far: 53296.9
Deduct 7200 from 7420 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
800 goes into 2200 2 times with a remainder of 600.
Record the quotient 2 as the next digit in the result. 
Result so far: 53296.92
Subtract 1600 from 2200 to get 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:
The number 800 fits into 6000 7 times, leaving a remainder of 400.
Use 7 as the next digit of our solution. 
Result so far: 53296.927
Subtract 5600 from 6000 to 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.

On to step 12:
The number 800 fits into 4000 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 53296.9275
If we take 4000 away from 4000, we end up 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 13:
If we divide 0 by 800, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 53296.9275
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.

Going ahead to step 14:
800 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 53296.9275
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 quotient of the division is 53296.9275, and the remainder is 0.0.
