We look at the division of 78584099 by 747 
Let's see how many times 747 fits into 78584099.

Moving on to step 1:
7 divided by 747 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 747

Advancing to step 2:
747 can be fit into 78 0 times, resulting in 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.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 747

Going ahead to step 3:
747 can be fit into 785 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 747 from 785 leaves us with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 747

Step 4:
The number 747 fits into 388 0 times, leaving a remainder of 388.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 388 after subtracting 0 from 388.
Bring next digit (4) of the dividend behind the 388 and repeat the process: 3884 / 747

Going ahead to step 5:
When dividing 3884 by 747, we get 5 with a remainder of 149.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 3735 away from 3884, we end up with 149.
Grab the next digit (0) from the dividend, add it to 149, then carry on: 1490 / 747

On to step 6:
747 goes into 1490 1 times with a remainder of 743.
Write down 1 as next digit of the result. 
Result so far: 1051.0
Subtracting 747 from 1490 leaves us with 743.
Take the next digit (9) from the dividend and append it to 743, then repeat: 7439 / 747

Let's proceed to step 7:
747 goes into 7439 9 times with a remainder of 716.
The number 9 becomes the next digit in our result. 
Result so far: 10519.0
Deduct 6723 from 7439 and we're left with 716.
Fetch the next digit (9) from the dividend, attach it to 716 and continue: 7169 / 747

Step 8:
747 can be fit into 7169 9 times, resulting in a remainder of 446.
Write down 9 as next digit of the result. 
Result so far: 105199.0
If we subtract 6723 from 7169, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 9:
The number 747 fits into 4460 5 times, leaving a remainder of 725.
Write down 5 as next digit of the result. 
Result so far: 105199.5
The remainder is 725 after subtracting 3735 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Moving on to step 10:
747 goes into 7250 9 times with a remainder of 527.
Write down 9 as next digit of the result. 
Result so far: 105199.59
The remainder is 527 after subtracting 6723 from 7250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Step 11:
When dividing 5270 by 747, we get 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 105199.597
The remainder is 41 after subtracting 5229 from 5270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
747 can be fit into 410 0 times, resulting in a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 105199.597
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 13:
When dividing 4100 by 747, we get 5 with a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 105199.59705
Subtract 3735 from 4100 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 14:
The number 747 fits into 3650 4 times, leaving a remainder of 662.
Put 4 as the next digit of the answer. 
Result so far: 105199.597054
The remainder is 662 after subtracting 2988 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 15:
6620 divided by 747 is 8 with a remainder of 644.
Put 8 as the next digit of the answer. 
Result so far: 105199.5970548
Deduct 5976 from 6620 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 16:
If we divide 6440 by 747, we get 8 and a remainder of 464.
The next digit of our result is 8. 
Result so far: 105199.59705488
If we subtract 5976 from 6440, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final result is 105199.59705488 with a remainder of 4.64e-07.
