We look at the division of 78621595 by 671 
We want to figure out the number of times 78621595 can be divided by 671.

Going ahead to step 1:
671 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 subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 671

Going ahead to step 2:
The number 671 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 671

Let's proceed to step 3:
If we divide 786 by 671, we get 1 and a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 671 from 786 to get 115.
Include the next digit (2) from the dividend after 115, then repeat: 1152 / 671

On to step 4:
1152 divided by 671 is 1 with a remainder of 481.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 481 after subtracting 671 from 1152.
Append the next digit (1) from the dividend to 481 and continue with: 4811 / 671

Advancing to step 5:
When dividing 4811 by 671, we get 7 with a remainder of 114.
The next digit of our result is 7. 
Result so far: 117.0
Subtracting 4697 from 4811 leaves us with 114.
Bring next digit (5) of the dividend behind the 114 and repeat the process: 1145 / 671

Let's proceed to step 6:
671 goes into 1145 1 times with a remainder of 474.
The number 1 becomes the next digit in our result. 
Result so far: 1171.0
Deduct 671 from 1145 and we're left with 474.
Bring next digit (9) of the dividend behind the 474 and repeat the process: 4749 / 671

Step 7:
When dividing 4749 by 671, we get 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 11717.0
Subtracting 4697 from 4749 leaves us with 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 671

Advancing to step 8:
The number 671 fits into 525 0 times, leaving a remainder of 525.
Record the quotient 0 as the next digit in the result. 
Result so far: 117170.0
Subtracting 0 from 525 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 9:
5250 divided by 671 is 7 with a remainder of 553.
The number 7 becomes the next digit in our result. 
Result so far: 117170.7
Subtracting 4697 from 5250 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

On to step 10:
The number 671 fits into 5530 8 times, leaving a remainder of 162.
Put 8 as the next digit of the answer. 
Result so far: 117170.78
Subtracting 5368 from 5530 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 11:
The number 671 fits into 1620 2 times, leaving a remainder of 278.
Write down 2 as next digit of the result. 
Result so far: 117170.782
The remainder is 278 after subtracting 1342 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 12:
The number 671 fits into 2780 4 times, leaving a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 117170.7824
The remainder is 96 after subtracting 2684 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
When dividing 960 by 671, we get 1 with a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 117170.78241
Deduct 671 from 960 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 14:
671 goes into 2890 4 times with a remainder of 206.
Put 4 as the next digit of the answer. 
Result so far: 117170.782414
Subtracting 2684 from 2890 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 15:
2060 divided by 671 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 117170.7824143
Subtract 2013 from 2060 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 16:
When dividing 470 by 671, we get 0 with a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 117170.7824143
Deduct 0 from 470 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final result is 117170.7824143 with a remainder of 4.7e-07.
