We divide 91907867 by 642
We want to divide 91907867 by 642.

On to step 1:
The number 642 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 642

Advancing to step 2:
642 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (9) from the dividend to 91 and continue with: 919 / 642

Going ahead to step 3:
919 divided by 642 is 1 with a remainder of 277.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 642 from 919, we get 277.
Fetch the next digit (0) from the dividend, attach it to 277 and continue: 2770 / 642

Let's proceed to step 4:
642 can be fit into 2770 4 times, resulting in a remainder of 202.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2568 from 2770 leaves us with 202.
Include the next digit (7) from the dividend after 202, then repeat: 2027 / 642

Advancing to step 5:
The number 642 fits into 2027 3 times, leaving a remainder of 101.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtract 1926 from 2027 to get 101.
Take the next digit (8) from the dividend and append it to 101, then repeat: 1018 / 642

Step 6:
The number 642 fits into 1018 1 times, leaving a remainder of 376.
The number 1 becomes the next digit in our result. 
Result so far: 1431.0
The remainder is 376 after subtracting 642 from 1018.
Take the next digit (6) from the dividend and append it to 376, then repeat: 3766 / 642

On to step 7:
642 can be fit into 3766 5 times, resulting in a remainder of 556.
The number 5 becomes the next digit in our result. 
Result so far: 14315.0
If we subtract 3210 from 3766, we get 556.
Take the next digit (7) from the dividend and append it to 556, then repeat: 5567 / 642

Let's proceed to step 8:
642 can be fit into 5567 8 times, resulting in a remainder of 431.
Write down 8 as next digit of the result. 
Result so far: 143158.0
If we take 5136 away from 5567, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 9:
642 goes into 4310 6 times with a remainder of 458.
The next digit of our result is 6. 
Result so far: 143158.6
The remainder is 458 after subtracting 3852 from 4310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 10:
642 can be fit into 4580 7 times, resulting in a remainder of 86.
The number 7 becomes the next digit in our result. 
Result so far: 143158.67
Subtract 4494 from 4580 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 11:
If we divide 860 by 642, we get 1 and a remainder of 218.
Put 1 as the next digit of the answer. 
Result so far: 143158.671
Subtracting 642 from 860 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 12:
2180 divided by 642 is 3 with a remainder of 254.
Put 3 as the next digit of the answer. 
Result so far: 143158.6713
The remainder is 254 after subtracting 1926 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 13:
When dividing 2540 by 642, we get 3 with a remainder of 614.
The next digit of our result is 3. 
Result so far: 143158.67133
Subtract 1926 from 2540 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

After the division, we end up with 143158.67133 and a remainder of 0.000614.
