We look at the division of 91061340 by 642 
We want to divide 91061340 by 642.

Step 1:
642 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 642

Step 2:
The number 642 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 642

Advancing to step 3:
If we divide 910 by 642, we get 1 and a remainder of 268.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 642 from 910 to get 268.
Fetch the next digit (6) from the dividend, attach it to 268 and continue: 2686 / 642

Let's proceed to step 4:
When dividing 2686 by 642, we get 4 with a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2568 away from 2686, we end up with 118.
Grab the next digit (1) from the dividend, add it to 118, then carry on: 1181 / 642

On to step 5:
1181 divided by 642 is 1 with a remainder of 539.
The next digit of our result is 1. 
Result so far: 141.0
Subtracting 642 from 1181 leaves us with 539.
Append the next digit (3) from the dividend to 539 and continue with: 5393 / 642

On to step 6:
642 goes into 5393 8 times with a remainder of 257.
The next digit of our result is 8. 
Result so far: 1418.0
If we subtract 5136 from 5393, we get 257.
Fetch the next digit (4) from the dividend, attach it to 257 and continue: 2574 / 642

Step 7:
642 can be fit into 2574 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 14184.0
If we subtract 2568 from 2574, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 642

Advancing to step 8:
60 divided by 642 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 141840.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 642, we get 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 141840.0
Deduct 0 from 600 and we're left 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.

Going ahead to step 10:
The number 642 fits into 6000 9 times, leaving a remainder of 222.
The next digit of our result is 9. 
Result so far: 141840.09
The remainder is 222 after subtracting 5778 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 11:
The number 642 fits into 2220 3 times, leaving a remainder of 294.
Write down 3 as next digit of the result. 
Result so far: 141840.093
Subtract 1926 from 2220 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 12:
642 can be fit into 2940 4 times, resulting in a remainder of 372.
The number 4 becomes the next digit in our result. 
Result so far: 141840.0934
If we take 2568 away from 2940, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 13:
642 goes into 3720 5 times with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 141840.09345
If we take 3210 away from 3720, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 14:
642 can be fit into 5100 7 times, resulting in a remainder of 606.
Write down 7 as next digit of the result. 
Result so far: 141840.093457
If we take 4494 away from 5100, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Advancing to step 15:
The number 642 fits into 6060 9 times, leaving a remainder of 282.
Put 9 as the next digit of the answer. 
Result so far: 141840.0934579
Deduct 5778 from 6060 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 16:
642 can be fit into 2820 4 times, resulting in a remainder of 252.
The next digit of our result is 4. 
Result so far: 141840.09345794
If we take 2568 away from 2820, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final result is 141840.09345794 with a remainder of 2.52e-07.
