10511862 ÷ 642 
We're looking to find how many times 642 goes into 10511862.

Moving on to step 1:
The number 642 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 642

Going ahead to step 2:
If we divide 10 by 642, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 642

Step 3:
If we divide 105 by 642, we get 0 and a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 105, we end up with 105.
Append the next digit (1) from the dividend to 105 and continue with: 1051 / 642

On to step 4:
642 goes into 1051 1 times with a remainder of 409.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 642 from 1051 to get 409.
Fetch the next digit (1) from the dividend, attach it to 409 and continue: 4091 / 642

Step 5:
642 can be fit into 4091 6 times, resulting in a remainder of 239.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 3852 from 4091 and we're left with 239.
Include the next digit (8) from the dividend after 239, then repeat: 2398 / 642

Advancing to step 6:
The number 642 fits into 2398 3 times, leaving a remainder of 472.
Put 3 as the next digit of the answer. 
Result so far: 163.0
The remainder is 472 after subtracting 1926 from 2398.
Bring next digit (6) of the dividend behind the 472 and repeat the process: 4726 / 642

Moving on to step 7:
The number 642 fits into 4726 7 times, leaving a remainder of 232.
The next digit of our result is 7. 
Result so far: 1637.0
The remainder is 232 after subtracting 4494 from 4726.
Take the next digit (2) from the dividend and append it to 232, then repeat: 2322 / 642

Advancing to step 8:
The number 642 fits into 2322 3 times, leaving a remainder of 396.
Write down 3 as next digit of the result. 
Result so far: 16373.0
The remainder is 396 after subtracting 1926 from 2322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 9:
3960 divided by 642 is 6 with a remainder of 108.
The next digit of our result is 6. 
Result so far: 16373.6
If we subtract 3852 from 3960, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 10:
The number 642 fits into 1080 1 times, leaving a remainder of 438.
The next digit of our result is 1. 
Result so far: 16373.61
Deduct 642 from 1080 and we're left with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 11:
If we divide 4380 by 642, we get 6 and a remainder of 528.
Record the quotient 6 as the next digit in the result. 
Result so far: 16373.616
If we take 3852 away from 4380, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 12:
5280 divided by 642 is 8 with a remainder of 144.
Record the quotient 8 as the next digit in the result. 
Result so far: 16373.6168
Deduct 5136 from 5280 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
The number 642 fits into 1440 2 times, leaving a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 16373.61682
Deduct 1284 from 1440 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 14:
When dividing 1560 by 642, we get 2 with a remainder of 276.
Use 2 as the next digit of our solution. 
Result so far: 16373.616822
If we take 1284 away from 1560, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 16373.616822 and a remainder of 2.76e-05.
