81125103 ÷ 173 
We're looking to find how many times 173 goes into 81125103.

Advancing to step 1:
173 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 173

On to step 2:
If we divide 81 by 173, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 173

Step 3:
The number 173 fits into 811 4 times, leaving a remainder of 119.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 692 from 811 and we're left with 119.
Append the next digit (2) from the dividend to 119 and continue with: 1192 / 173

Going ahead to step 4:
When dividing 1192 by 173, we get 6 with a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 154 after subtracting 1038 from 1192.
Bring next digit (5) of the dividend behind the 154 and repeat the process: 1545 / 173

Going ahead to step 5:
173 goes into 1545 8 times with a remainder of 161.
Put 8 as the next digit of the answer. 
Result so far: 468.0
Subtract 1384 from 1545 to get 161.
Bring next digit (1) of the dividend behind the 161 and repeat the process: 1611 / 173

Moving on to step 6:
When dividing 1611 by 173, we get 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 4689.0
Deduct 1557 from 1611 and we're left with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 173

Step 7:
The number 173 fits into 540 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 46893.0
The remainder is 21 after subtracting 519 from 540.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 173

Going ahead to step 8:
173 goes into 213 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 468931.0
Subtracting 173 from 213 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
173 can be fit into 400 2 times, resulting in a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 468931.2
If we take 346 away from 400, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
173 can be fit into 540 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 468931.23
If we take 519 away from 540, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
210 divided by 173 is 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 468931.231
The remainder is 37 after subtracting 173 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
370 divided by 173 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 468931.2312
Deduct 346 from 370 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
240 divided by 173 is 1 with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 468931.23121
Deduct 173 from 240 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
670 divided by 173 is 3 with a remainder of 151.
The next digit of our result is 3. 
Result so far: 468931.231213
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.

On to step 15:
If we divide 1510 by 173, we get 8 and a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 468931.2312138
If we take 1384 away from 1510, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 16:
173 goes into 1260 7 times with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 468931.23121387
Subtract 1211 from 1260 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 468931.23121387 with a remainder of 4.9e-08.
