We're dividing 80042607 by 170 
We want to divide 80042607 by 170.

Advancing to step 1:
If we divide 8 by 170, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 170

Let's proceed to step 2:
When dividing 80 by 170, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 170

On to step 3:
When dividing 800 by 170, we get 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 120 after subtracting 680 from 800.
Grab the next digit (4) from the dividend, add it to 120, then carry on: 1204 / 170

Let's proceed to step 4:
170 goes into 1204 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 1190 away from 1204, we end up with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 170

Moving on to step 5:
When dividing 142 by 170, we get 0 with a remainder of 142.
Use 0 as the next digit of our solution. 
Result so far: 470.0
Deduct 0 from 142 and we're left with 142.
Append the next digit (6) from the dividend to 142 and continue with: 1426 / 170

Going ahead to step 6:
When dividing 1426 by 170, we get 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 4708.0
Subtract 1360 from 1426 to get 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 170

Let's proceed to step 7:
170 goes into 660 3 times with a remainder of 150.
Put 3 as the next digit of the answer. 
Result so far: 47083.0
If we subtract 510 from 660, we get 150.
Include the next digit (7) from the dividend after 150, then repeat: 1507 / 170

Advancing to step 8:
1507 divided by 170 is 8 with a remainder of 147.
Write down 8 as next digit of the result. 
Result so far: 470838.0
Subtracting 1360 from 1507 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 9:
1470 divided by 170 is 8 with a remainder of 110.
Write down 8 as next digit of the result. 
Result so far: 470838.8
If we subtract 1360 from 1470, we 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.

Advancing to step 10:
When dividing 1100 by 170, we get 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 470838.86
Deduct 1020 from 1100 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
170 goes into 800 4 times with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 470838.864
If we subtract 680 from 800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
1200 divided by 170 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 470838.8647
Subtract 1190 from 1200 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 170, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 470838.8647
If we subtract 0 from 100, we 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.

Moving on to step 14:
170 goes into 1000 5 times with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 470838.864705
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.

Going ahead to step 15:
170 goes into 1500 8 times with a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 470838.8647058
Subtracting 1360 from 1500 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
When dividing 1400 by 170, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 470838.86470588
Subtracting 1360 from 1400 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.

In conclusion, the division gives 470838.86470588 with a balance of 4e-08.
