Let's divide 80631215 by 173
We want to divide 80631215 by 173.

Step 1:
The number 173 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 173

Moving on to step 2:
173 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 173

Step 3:
When dividing 806 by 173, we get 4 with a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 692 from 806 to get 114.
Grab the next digit (3) from the dividend, add it to 114, then carry on: 1143 / 173

On to step 4:
When dividing 1143 by 173, we get 6 with a remainder of 105.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 1038 from 1143 and we're left with 105.
Fetch the next digit (1) from the dividend, attach it to 105 and continue: 1051 / 173

Let's proceed to step 5:
173 goes into 1051 6 times with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
Subtracting 1038 from 1051 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 173

Let's proceed to step 6:
The number 173 fits into 132 0 times, leaving a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 4660.0
If we subtract 0 from 132, we get 132.
Append the next digit (1) from the dividend to 132 and continue with: 1321 / 173

Advancing to step 7:
173 goes into 1321 7 times with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 46607.0
Deduct 1211 from 1321 and we're left with 110.
Append the next digit (5) from the dividend to 110 and continue with: 1105 / 173

On to step 8:
173 can be fit into 1105 6 times, resulting in a remainder of 67.
Use 6 as the next digit of our solution. 
Result so far: 466076.0
If we subtract 1038 from 1105, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
If we divide 670 by 173, we get 3 and a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 466076.3
Subtracting 519 from 670 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 10:
173 can be fit into 1510 8 times, resulting in a remainder of 126.
The next digit of our result is 8. 
Result so far: 466076.38
Subtract 1384 from 1510 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 11:
When dividing 1260 by 173, we get 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 466076.387
Deduct 1211 from 1260 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
When dividing 490 by 173, we get 2 with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 466076.3872
The remainder is 144 after subtracting 346 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
1440 divided by 173 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 466076.38728
If we take 1384 away from 1440, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
If we divide 560 by 173, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 466076.387283
Subtract 519 from 560 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 15:
410 divided by 173 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 466076.3872832
If we subtract 346 from 410, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
173 goes into 640 3 times with a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 466076.38728323
Subtracting 519 from 640 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The final result is 466076.38728323 with a remainder of 1.21e-07.
