80769336 divided by 642 
We're looking to find how many times 642 goes into 80769336.

Going ahead to step 1:
642 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 642

Advancing to step 2:
The number 642 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 642

Going ahead to step 3:
If we divide 807 by 642, we get 1 and a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 642 from 807 to get 165.
Fetch the next digit (6) from the dividend, attach it to 165 and continue: 1656 / 642

Going ahead to step 4:
If we divide 1656 by 642, we get 2 and a remainder of 372.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1284 away from 1656, we end up with 372.
Bring next digit (9) of the dividend behind the 372 and repeat the process: 3729 / 642

On to step 5:
642 goes into 3729 5 times with a remainder of 519.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 519 after subtracting 3210 from 3729.
Include the next digit (3) from the dividend after 519, then repeat: 5193 / 642

Advancing to step 6:
642 goes into 5193 8 times with a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 1258.0
If we take 5136 away from 5193, we end up with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 642

Going ahead to step 7:
When dividing 573 by 642, we get 0 with a remainder of 573.
Write down 0 as next digit of the result. 
Result so far: 12580.0
The remainder is 573 after subtracting 0 from 573.
Take the next digit (6) from the dividend and append it to 573, then repeat: 5736 / 642

Step 8:
The number 642 fits into 5736 8 times, leaving a remainder of 600.
Use 8 as the next digit of our solution. 
Result so far: 125808.0
If we take 5136 away from 5736, we end up 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.

On to step 9:
If we divide 6000 by 642, we get 9 and a remainder of 222.
Record the quotient 9 as the next digit in the result. 
Result so far: 125808.9
Deduct 5778 from 6000 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 10:
The number 642 fits into 2220 3 times, leaving a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 125808.93
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 11:
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: 125808.934
Subtracting 2568 from 2940 leaves us 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.

Moving on to step 12:
3720 divided by 642 is 5 with a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 125808.9345
Subtract 3210 from 3720 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 13:
When dividing 5100 by 642, we get 7 with a remainder of 606.
The next digit of our result is 7. 
Result so far: 125808.93457
Deduct 4494 from 5100 and we're left 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.

Going ahead to step 14:
642 goes into 6060 9 times with a remainder of 282.
Use 9 as the next digit of our solution. 
Result so far: 125808.934579
Subtracting 5778 from 6060 leaves us 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.

Let's proceed to step 15:
642 can be fit into 2820 4 times, resulting in a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 125808.9345794
Subtract 2568 from 2820 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 16:
642 goes into 2520 3 times with a remainder of 594.
Put 3 as the next digit of the answer. 
Result so far: 125808.93457943
If we take 1926 away from 2520, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Our division results in 125808.93457943 with a remaining 5.94e-07.
