We're dividing 77329617 by 172 
We want to divide 77329617 by 172.

Going ahead to step 1:
If we divide 7 by 172, we get 0 and 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.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 172

Going ahead to step 2:
172 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 172

Advancing to step 3:
172 goes into 773 4 times with a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 688 away from 773, we end up with 85.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 172

Going ahead to step 4:
If we divide 852 by 172, we get 4 and a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 688 from 852, we get 164.
Grab the next digit (9) from the dividend, add it to 164, then carry on: 1649 / 172

Advancing to step 5:
172 goes into 1649 9 times with a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 449.0
Subtracting 1548 from 1649 leaves us with 101.
Fetch the next digit (6) from the dividend, attach it to 101 and continue: 1016 / 172

Step 6:
1016 divided by 172 is 5 with a remainder of 156.
The next digit of our result is 5. 
Result so far: 4495.0
Subtract 860 from 1016 to get 156.
Grab the next digit (1) from the dividend, add it to 156, then carry on: 1561 / 172

Going ahead to step 7:
1561 divided by 172 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 44959.0
Subtract 1548 from 1561 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 172

Let's proceed to step 8:
The number 172 fits into 137 0 times, leaving a remainder of 137.
Record the quotient 0 as the next digit in the result. 
Result so far: 449590.0
If we subtract 0 from 137, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
The number 172 fits into 1370 7 times, leaving a remainder of 166.
Use 7 as the next digit of our solution. 
Result so far: 449590.7
Deduct 1204 from 1370 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 10:
The number 172 fits into 1660 9 times, leaving a remainder of 112.
The number 9 becomes the next digit in our result. 
Result so far: 449590.79
The remainder is 112 after subtracting 1548 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 11:
When dividing 1120 by 172, we get 6 with a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 449590.796
If we subtract 1032 from 1120, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
If we divide 880 by 172, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 449590.7965
Deduct 860 from 880 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 172, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 449590.79651
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
172 can be fit into 280 1 times, resulting in a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 449590.796511
Subtracting 172 from 280 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 449590.796511, with a leftover of 1.08e-05.
