We look at the division of 80241396 by 642 
We want to figure out the number of times 80241396 can be divided by 642.

Let's proceed to step 1:
When dividing 8 by 642, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 642

Going ahead to step 2:
642 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 642

Advancing to step 3:
When dividing 802 by 642, we get 1 with a remainder of 160.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 642 from 802 and we're left with 160.
Take the next digit (4) from the dividend and append it to 160, then repeat: 1604 / 642

On to step 4:
642 can be fit into 1604 2 times, resulting in a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1284 from 1604, we get 320.
Grab the next digit (1) from the dividend, add it to 320, then carry on: 3201 / 642

Moving on to step 5:
The number 642 fits into 3201 4 times, leaving a remainder of 633.
The next digit of our result is 4. 
Result so far: 124.0
The remainder is 633 after subtracting 2568 from 3201.
Include the next digit (3) from the dividend after 633, then repeat: 6333 / 642

On to step 6:
642 goes into 6333 9 times with a remainder of 555.
Record the quotient 9 as the next digit in the result. 
Result so far: 1249.0
If we subtract 5778 from 6333, we get 555.
Take the next digit (9) from the dividend and append it to 555, then repeat: 5559 / 642

Advancing to step 7:
642 can be fit into 5559 8 times, resulting in a remainder of 423.
Put 8 as the next digit of the answer. 
Result so far: 12498.0
Subtracting 5136 from 5559 leaves us with 423.
Append the next digit (6) from the dividend to 423 and continue with: 4236 / 642

Moving on to step 8:
If we divide 4236 by 642, we get 6 and a remainder of 384.
The next digit of our result is 6. 
Result so far: 124986.0
If we take 3852 away from 4236, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 9:
642 goes into 3840 5 times with a remainder of 630.
Write down 5 as next digit of the result. 
Result so far: 124986.5
Deduct 3210 from 3840 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 10:
The number 642 fits into 6300 9 times, leaving a remainder of 522.
The next digit of our result is 9. 
Result so far: 124986.59
If we take 5778 away from 6300, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 11:
The number 642 fits into 5220 8 times, leaving a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 124986.598
The remainder is 84 after subtracting 5136 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
If we divide 840 by 642, we get 1 and a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 124986.5981
If we take 642 away from 840, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 13:
When dividing 1980 by 642, we get 3 with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 124986.59813
Deduct 1926 from 1980 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
The number 642 fits into 540 0 times, leaving a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 124986.59813
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 15:
642 goes into 5400 8 times with a remainder of 264.
The number 8 becomes the next digit in our result. 
Result so far: 124986.5981308
Subtract 5136 from 5400 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 16:
2640 divided by 642 is 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 124986.59813084
If we subtract 2568 from 2640, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 124986.59813084 with a remainder of 7.2e-08.
