Let's divide 78841099 by 647
We're looking to find how many times 647 goes into 78841099.

Step 1:
647 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 647

Let's proceed to step 2:
When dividing 78 by 647, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 647

Advancing to step 3:
When dividing 788 by 647, we get 1 with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 647 from 788 leaves us with 141.
Fetch the next digit (4) from the dividend, attach it to 141 and continue: 1414 / 647

Going ahead to step 4:
647 goes into 1414 2 times with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1294 away from 1414, we end up with 120.
Append the next digit (1) from the dividend to 120 and continue with: 1201 / 647

Advancing to step 5:
When dividing 1201 by 647, we get 1 with a remainder of 554.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 647 away from 1201, we end up with 554.
Include the next digit (0) from the dividend after 554, then repeat: 5540 / 647

Going ahead to step 6:
5540 divided by 647 is 8 with a remainder of 364.
Record the quotient 8 as the next digit in the result. 
Result so far: 1218.0
Subtracting 5176 from 5540 leaves us with 364.
Take the next digit (9) from the dividend and append it to 364, then repeat: 3649 / 647

Going ahead to step 7:
647 can be fit into 3649 5 times, resulting in a remainder of 414.
The number 5 becomes the next digit in our result. 
Result so far: 12185.0
If we subtract 3235 from 3649, we get 414.
Append the next digit (9) from the dividend to 414 and continue with: 4149 / 647

Going ahead to step 8:
When dividing 4149 by 647, we get 6 with a remainder of 267.
Put 6 as the next digit of the answer. 
Result so far: 121856.0
If we subtract 3882 from 4149, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 9:
647 can be fit into 2670 4 times, resulting in a remainder of 82.
The next digit of our result is 4. 
Result so far: 121856.4
If we take 2588 away from 2670, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
647 goes into 820 1 times with a remainder of 173.
Put 1 as the next digit of the answer. 
Result so far: 121856.41
If we subtract 647 from 820, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 11:
647 can be fit into 1730 2 times, resulting in a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 121856.412
If we subtract 1294 from 1730, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 12:
When dividing 4360 by 647, we get 6 with a remainder of 478.
The number 6 becomes the next digit in our result. 
Result so far: 121856.4126
Deduct 3882 from 4360 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 13:
4780 divided by 647 is 7 with a remainder of 251.
Use 7 as the next digit of our solution. 
Result so far: 121856.41267
Subtracting 4529 from 4780 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 14:
647 goes into 2510 3 times with a remainder of 569.
The next digit of our result is 3. 
Result so far: 121856.412673
Deduct 1941 from 2510 and we're left with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Moving on to step 15:
5690 divided by 647 is 8 with a remainder of 514.
The number 8 becomes the next digit in our result. 
Result so far: 121856.4126738
If we take 5176 away from 5690, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 16:
647 can be fit into 5140 7 times, resulting in a remainder of 611.
The next digit of our result is 7. 
Result so far: 121856.41267387
Subtract 4529 from 5140 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

The final result is 121856.41267387 with a remainder of 6.11e-07.
