81530371 ÷ 170 
We want to divide 81530371 by 170.

Going ahead to step 1:
The number 170 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 170

Moving on to step 2:
81 divided by 170 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 170

Advancing to step 3:
170 can be fit into 815 4 times, resulting in a remainder of 135.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 680 from 815 leaves us with 135.
Bring next digit (3) of the dividend behind the 135 and repeat the process: 1353 / 170

Let's proceed to step 4:
When dividing 1353 by 170, we get 7 with a remainder of 163.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 163 after subtracting 1190 from 1353.
Fetch the next digit (0) from the dividend, attach it to 163 and continue: 1630 / 170

Advancing to step 5:
When dividing 1630 by 170, we get 9 with a remainder of 100.
Write down 9 as next digit of the result. 
Result so far: 479.0
Subtract 1530 from 1630 to get 100.
Append the next digit (3) from the dividend to 100 and continue with: 1003 / 170

Advancing to step 6:
When dividing 1003 by 170, we get 5 with a remainder of 153.
Record the quotient 5 as the next digit in the result. 
Result so far: 4795.0
Subtracting 850 from 1003 leaves us with 153.
Bring next digit (7) of the dividend behind the 153 and repeat the process: 1537 / 170

Going ahead to step 7:
1537 divided by 170 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 47959.0
If we take 1530 away from 1537, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 170

Advancing to step 8:
170 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 479590.0
Subtract 0 from 71 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
The number 170 fits into 710 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 479590.4
Deduct 680 from 710 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 170, we get 1 with a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 479590.41
The remainder is 130 after subtracting 170 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
The number 170 fits into 1300 7 times, leaving a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 479590.417
The remainder is 110 after subtracting 1190 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 12:
170 can be fit into 1100 6 times, resulting in a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 479590.4176
If we subtract 1020 from 1100, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
If we divide 800 by 170, we get 4 and a remainder of 120.
The next digit of our result is 4. 
Result so far: 479590.41764
If we take 680 away from 800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
If we divide 1200 by 170, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 479590.417647
Deduct 1190 from 1200 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
The number 170 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 479590.417647
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
When dividing 1000 by 170, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 479590.41764705
The remainder is 150 after subtracting 850 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 479590.41764705 and a remainder of 1.5e-07.
