We look at the division of 78387116 by 173 
We want to figure out the number of times 78387116 can be divided by 173.

Going ahead to step 1:
173 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 173

On to step 2:
173 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 173

On to step 3:
783 divided by 173 is 4 with a remainder of 91.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 692 from 783 and we're left with 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 173

Step 4:
The number 173 fits into 918 5 times, leaving a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 865 from 918 to get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 173

Going ahead to step 5:
When dividing 537 by 173, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 453.0
Deduct 519 from 537 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 173

Let's proceed to step 6:
173 goes into 181 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 4531.0
If we subtract 173 from 181, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 173

On to step 7:
81 divided by 173 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 45310.0
If we take 0 away from 81, we end up with 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 173

Moving on to step 8:
173 goes into 816 4 times with a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 453104.0
Subtract 692 from 816 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
When dividing 1240 by 173, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 453104.7
If we take 1211 away from 1240, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
173 can be fit into 290 1 times, resulting in a remainder of 117.
The next digit of our result is 1. 
Result so far: 453104.71
If we take 173 away from 290, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 11:
173 can be fit into 1170 6 times, resulting in a remainder of 132.
The next digit of our result is 6. 
Result so far: 453104.716
The remainder is 132 after subtracting 1038 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 12:
173 goes into 1320 7 times with a remainder of 109.
Write down 7 as next digit of the result. 
Result so far: 453104.7167
Deduct 1211 from 1320 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 13:
173 goes into 1090 6 times with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 453104.71676
Subtracting 1038 from 1090 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
The number 173 fits into 520 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 453104.716763
Deduct 519 from 520 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 15:
10 divided by 173 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 453104.716763
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
173 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 453104.716763
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 453104.716763, and the remainder is 1e-07.
