42251767 divided by 321 
We want to divide 42251767 by 321.

Advancing to step 1:
321 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.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 321

Going ahead to step 2:
42 divided by 321 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 321

Going ahead to step 3:
321 goes into 422 1 times with a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 101 after subtracting 321 from 422.
Fetch the next digit (5) from the dividend, attach it to 101 and continue: 1015 / 321

Going ahead to step 4:
The number 321 fits into 1015 3 times, leaving a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 52 after subtracting 963 from 1015.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 321

Going ahead to step 5:
521 divided by 321 is 1 with a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we subtract 321 from 521, we get 200.
Include the next digit (7) from the dividend after 200, then repeat: 2007 / 321

Let's proceed to step 6:
2007 divided by 321 is 6 with a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 1316.0
Deduct 1926 from 2007 and we're left with 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 321

Step 7:
If we divide 816 by 321, we get 2 and a remainder of 174.
Write down 2 as next digit of the result. 
Result so far: 13162.0
If we subtract 642 from 816, we get 174.
Grab the next digit (7) from the dividend, add it to 174, then carry on: 1747 / 321

Step 8:
The number 321 fits into 1747 5 times, leaving a remainder of 142.
Use 5 as the next digit of our solution. 
Result so far: 131625.0
Subtracting 1605 from 1747 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 9:
321 can be fit into 1420 4 times, resulting in a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 131625.4
If we take 1284 away from 1420, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
The number 321 fits into 1360 4 times, leaving a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 131625.44
The remainder is 76 after subtracting 1284 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 131625.44, with a leftover of 0.076.
