84080192 ÷ 790 
We want to figure out the number of times 84080192 can be divided by 790.

Step 1:
When dividing 8 by 790, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 790

Going ahead to step 2:
When dividing 84 by 790, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 790

On to step 3:
790 can be fit into 840 1 times, resulting in a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 790 from 840 and we're left with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 790

On to step 4:
The number 790 fits into 508 0 times, leaving a remainder of 508.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 508 after subtracting 0 from 508.
Include the next digit (0) from the dividend after 508, then repeat: 5080 / 790

Moving on to step 5:
The number 790 fits into 5080 6 times, leaving a remainder of 340.
The next digit of our result is 6. 
Result so far: 106.0
If we subtract 4740 from 5080, we get 340.
Take the next digit (1) from the dividend and append it to 340, then repeat: 3401 / 790

Step 6:
If we divide 3401 by 790, we get 4 and a remainder of 241.
Use 4 as the next digit of our solution. 
Result so far: 1064.0
Deduct 3160 from 3401 and we're left with 241.
Grab the next digit (9) from the dividend, add it to 241, then carry on: 2419 / 790

On to step 7:
2419 divided by 790 is 3 with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 10643.0
The remainder is 49 after subtracting 2370 from 2419.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 790

Moving on to step 8:
790 can be fit into 492 0 times, resulting in a remainder of 492.
Use 0 as the next digit of our solution. 
Result so far: 106430.0
Deduct 0 from 492 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 9:
If we divide 4920 by 790, we get 6 and a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 106430.6
Subtracting 4740 from 4920 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
If we divide 1800 by 790, we get 2 and a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 106430.62
The remainder is 220 after subtracting 1580 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
When dividing 2200 by 790, we get 2 with a remainder of 620.
The next digit of our result is 2. 
Result so far: 106430.622
Deduct 1580 from 2200 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

After the division, we end up with 106430.622 and a remainder of 0.062.
