We're dividing 78774941 by 171 
We want to figure out the number of times 78774941 can be divided by 171.

Advancing to step 1:
7 divided by 171 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 171

Going ahead to step 2:
78 divided by 171 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 171

On to step 3:
787 divided by 171 is 4 with a remainder of 103.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 684 from 787 leaves us with 103.
Grab the next digit (7) from the dividend, add it to 103, then carry on: 1037 / 171

Going ahead to step 4:
171 goes into 1037 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 1026 from 1037 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 171

On to step 5:
The number 171 fits into 114 0 times, leaving a remainder of 114.
Use 0 as the next digit of our solution. 
Result so far: 460.0
Subtracting 0 from 114 leaves us with 114.
Fetch the next digit (9) from the dividend, attach it to 114 and continue: 1149 / 171

Advancing to step 6:
When dividing 1149 by 171, we get 6 with a remainder of 123.
The number 6 becomes the next digit in our result. 
Result so far: 4606.0
If we take 1026 away from 1149, we end up with 123.
Append the next digit (4) from the dividend to 123 and continue with: 1234 / 171

Step 7:
When dividing 1234 by 171, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 46067.0
If we take 1197 away from 1234, we end up with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 171

Let's proceed to step 8:
The number 171 fits into 371 2 times, leaving a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 460672.0
If we subtract 342 from 371, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
The number 171 fits into 290 1 times, leaving a remainder of 119.
The next digit of our result is 1. 
Result so far: 460672.1
The remainder is 119 after subtracting 171 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 10:
1190 divided by 171 is 6 with a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 460672.16
Subtract 1026 from 1190 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 11:
If we divide 1640 by 171, we get 9 and a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 460672.169
The remainder is 101 after subtracting 1539 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 12:
171 can be fit into 1010 5 times, resulting in a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 460672.1695
If we subtract 855 from 1010, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 13:
The number 171 fits into 1550 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 460672.16959
If we take 1539 away from 1550, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
171 goes into 110 0 times with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 460672.16959
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
When dividing 1100 by 171, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 460672.1695906
Deduct 1026 from 1100 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 16:
The number 171 fits into 740 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 460672.16959064
Subtract 684 from 740 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 460672.16959064, and the remainder is 5.6e-08.
