We divide 12664361 by 642
We want to divide 12664361 by 642.

Let's proceed 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 642

Advancing to step 2:
The number 642 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 642

Advancing to step 3:
642 can be fit into 126 0 times, resulting in a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Grab the next digit (6) from the dividend, add it to 126, then carry on: 1266 / 642

Advancing to step 4:
The number 642 fits into 1266 1 times, leaving a remainder of 624.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 642 away from 1266, we end up with 624.
Bring next digit (4) of the dividend behind the 624 and repeat the process: 6244 / 642

Moving on to step 5:
The number 642 fits into 6244 9 times, leaving a remainder of 466.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 5778 from 6244 and we're left with 466.
Append the next digit (3) from the dividend to 466 and continue with: 4663 / 642

Let's proceed to step 6:
642 goes into 4663 7 times with a remainder of 169.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtracting 4494 from 4663 leaves us with 169.
Bring next digit (6) of the dividend behind the 169 and repeat the process: 1696 / 642

Let's proceed to step 7:
642 goes into 1696 2 times with a remainder of 412.
Use 2 as the next digit of our solution. 
Result so far: 1972.0
Deduct 1284 from 1696 and we're left with 412.
Append the next digit (1) from the dividend to 412 and continue with: 4121 / 642

Advancing to step 8:
642 can be fit into 4121 6 times, resulting in a remainder of 269.
The number 6 becomes the next digit in our result. 
Result so far: 19726.0
Subtract 3852 from 4121 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 9:
642 goes into 2690 4 times with a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 19726.4
If we subtract 2568 from 2690, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 10:
642 can be fit into 1220 1 times, resulting in a remainder of 578.
Use 1 as the next digit of our solution. 
Result so far: 19726.41
The remainder is 578 after subtracting 642 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 11:
When dividing 5780 by 642, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19726.419
Subtracting 5778 from 5780 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
642 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19726.419
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 642 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 19726.419
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 19726.419 with a balance of 0.0002.
