We're dividing 79280548 by 642 
We're looking to find how many times 642 goes into 79280548.

Let's proceed to step 1:
If we divide 7 by 642, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 642

Advancing to step 2:
642 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Take the next digit (2) from the dividend and append it to 79, then repeat: 792 / 642

Moving on to step 3:
792 divided by 642 is 1 with a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 642 from 792 to get 150.
Grab the next digit (8) from the dividend, add it to 150, then carry on: 1508 / 642

Advancing to step 4:
1508 divided by 642 is 2 with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1284 from 1508 and we're left with 224.
Grab the next digit (0) from the dividend, add it to 224, then carry on: 2240 / 642

Step 5:
The number 642 fits into 2240 3 times, leaving a remainder of 314.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Deduct 1926 from 2240 and we're left with 314.
Grab the next digit (5) from the dividend, add it to 314, then carry on: 3145 / 642

Going ahead to step 6:
3145 divided by 642 is 4 with a remainder of 577.
The next digit of our result is 4. 
Result so far: 1234.0
The remainder is 577 after subtracting 2568 from 3145.
Bring next digit (4) of the dividend behind the 577 and repeat the process: 5774 / 642

On to step 7:
642 can be fit into 5774 8 times, resulting in a remainder of 638.
The next digit of our result is 8. 
Result so far: 12348.0
Subtracting 5136 from 5774 leaves us with 638.
Take the next digit (8) from the dividend and append it to 638, then repeat: 6388 / 642

Advancing to step 8:
If we divide 6388 by 642, we get 9 and a remainder of 610.
The next digit of our result is 9. 
Result so far: 123489.0
Subtracting 5778 from 6388 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 9:
642 goes into 6100 9 times with a remainder of 322.
Use 9 as the next digit of our solution. 
Result so far: 123489.9
The remainder is 322 after subtracting 5778 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
642 can be fit into 3220 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 123489.95
Subtract 3210 from 3220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 642, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 123489.95
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
1000 divided by 642 is 1 with a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 123489.9501
Subtract 642 from 1000 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 13:
When dividing 3580 by 642, we get 5 with a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 123489.95015
Subtract 3210 from 3580 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 14:
When dividing 3700 by 642, we get 5 with a remainder of 490.
The next digit of our result is 5. 
Result so far: 123489.950155
The remainder is 490 after subtracting 3210 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 123489.950155 with a balance of 4.9e-05.
