78815547 ÷ 702 
Let's see how many times 702 fits into 78815547.

Going ahead to step 1:
When dividing 7 by 702, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 702

Let's proceed to step 2:
When dividing 78 by 702, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 702

Advancing to step 3:
702 goes into 788 1 times with a remainder of 86.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 702 from 788 to get 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 702

Advancing to step 4:
The number 702 fits into 861 1 times, leaving a remainder of 159.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 702 from 861 leaves us with 159.
Include the next digit (5) from the dividend after 159, then repeat: 1595 / 702

On to step 5:
The number 702 fits into 1595 2 times, leaving a remainder of 191.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Subtract 1404 from 1595 to get 191.
Fetch the next digit (5) from the dividend, attach it to 191 and continue: 1915 / 702

Advancing to step 6:
The number 702 fits into 1915 2 times, leaving a remainder of 511.
The number 2 becomes the next digit in our result. 
Result so far: 1122.0
Subtract 1404 from 1915 to get 511.
Grab the next digit (4) from the dividend, add it to 511, then carry on: 5114 / 702

Let's proceed to step 7:
702 goes into 5114 7 times with a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 11227.0
If we take 4914 away from 5114, we end up with 200.
Grab the next digit (7) from the dividend, add it to 200, then carry on: 2007 / 702

Going ahead to step 8:
When dividing 2007 by 702, we get 2 with a remainder of 603.
Record the quotient 2 as the next digit in the result. 
Result so far: 112272.0
If we take 1404 away from 2007, we end up with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 9:
702 can be fit into 6030 8 times, resulting in a remainder of 414.
Write down 8 as next digit of the result. 
Result so far: 112272.8
If we subtract 5616 from 6030, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 10:
702 can be fit into 4140 5 times, resulting in a remainder of 630.
Write down 5 as next digit of the result. 
Result so far: 112272.85
Subtracting 3510 from 4140 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 11:
When dividing 6300 by 702, we get 8 with a remainder of 684.
Record the quotient 8 as the next digit in the result. 
Result so far: 112272.858
Subtracting 5616 from 6300 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 12:
If we divide 6840 by 702, we get 9 and a remainder of 522.
The next digit of our result is 9. 
Result so far: 112272.8589
If we take 6318 away from 6840, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 13:
702 can be fit into 5220 7 times, resulting in a remainder of 306.
Use 7 as the next digit of our solution. 
Result so far: 112272.85897
Deduct 4914 from 5220 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 14:
The number 702 fits into 3060 4 times, leaving a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 112272.858974
The remainder is 252 after subtracting 2808 from 3060.
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 15:
702 goes into 2520 3 times with a remainder of 414.
Write down 3 as next digit of the result. 
Result so far: 112272.8589743
If we subtract 2106 from 2520, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 16:
702 goes into 4140 5 times with a remainder of 630.
Put 5 as the next digit of the answer. 
Result so far: 112272.85897435
If we take 3510 away from 4140, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The final outcome is 112272.85897435, with a leftover of 6.3e-07.
