42279259 divided by 801 
Let's see how many times 801 fits into 42279259.

Let's proceed to step 1:
801 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 801

Advancing to step 2:
42 divided by 801 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 801

On to step 3:
When dividing 422 by 801, we get 0 with a remainder of 422.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 422 to get 422.
Include the next digit (7) from the dividend after 422, then repeat: 4227 / 801

Moving on to step 4:
4227 divided by 801 is 5 with a remainder of 222.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4005 from 4227 to get 222.
Bring next digit (9) of the dividend behind the 222 and repeat the process: 2229 / 801

Going ahead to step 5:
The number 801 fits into 2229 2 times, leaving a remainder of 627.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 1602 from 2229 and we're left with 627.
Grab the next digit (2) from the dividend, add it to 627, then carry on: 6272 / 801

On to step 6:
The number 801 fits into 6272 7 times, leaving a remainder of 665.
Use 7 as the next digit of our solution. 
Result so far: 527.0
Subtract 5607 from 6272 to get 665.
Fetch the next digit (5) from the dividend, attach it to 665 and continue: 6655 / 801

Advancing to step 7:
801 goes into 6655 8 times with a remainder of 247.
The number 8 becomes the next digit in our result. 
Result so far: 5278.0
If we take 6408 away from 6655, we end up with 247.
Append the next digit (9) from the dividend to 247 and continue with: 2479 / 801

On to step 8:
When dividing 2479 by 801, we get 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 52783.0
The remainder is 76 after subtracting 2403 from 2479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
If we divide 760 by 801, we get 0 and a remainder of 760.
Record the quotient 0 as the next digit in the result. 
Result so far: 52783.0
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 10:
801 can be fit into 7600 9 times, resulting in a remainder of 391.
Record the quotient 9 as the next digit in the result. 
Result so far: 52783.09
Subtracting 7209 from 7600 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 11:
The number 801 fits into 3910 4 times, leaving a remainder of 706.
The next digit of our result is 4. 
Result so far: 52783.094
Subtract 3204 from 3910 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 12:
The number 801 fits into 7060 8 times, leaving a remainder of 652.
Write down 8 as next digit of the result. 
Result so far: 52783.0948
If we take 6408 away from 7060, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 13:
801 goes into 6520 8 times with a remainder of 112.
The next digit of our result is 8. 
Result so far: 52783.09488
The remainder is 112 after subtracting 6408 from 6520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 52783.09488 and a remainder of 0.000112.
