We're dividing 91029443 by 170 
We want to divide 91029443 by 170.

On to step 1:
When dividing 9 by 170, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 170

On to step 2:
170 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 170

Step 3:
910 divided by 170 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 850 from 910 to get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 170

Going ahead to step 4:
If we divide 602 by 170, we get 3 and a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 510 from 602 leaves us with 92.
Grab the next digit (9) from the dividend, add it to 92, then carry on: 929 / 170

Going ahead to step 5:
929 divided by 170 is 5 with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 535.0
Subtract 850 from 929 to get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 170

Moving on to step 6:
170 goes into 794 4 times with a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 5354.0
Subtract 680 from 794 to get 114.
Fetch the next digit (4) from the dividend, attach it to 114 and continue: 1144 / 170

On to step 7:
When dividing 1144 by 170, we get 6 with a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 53546.0
Deduct 1020 from 1144 and we're left with 124.
Fetch the next digit (3) from the dividend, attach it to 124 and continue: 1243 / 170

On to step 8:
When dividing 1243 by 170, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 535467.0
If we subtract 1190 from 1243, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 9:
When dividing 530 by 170, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 535467.3
If we subtract 510 from 530, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 170 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 535467.31
The remainder is 30 after subtracting 170 from 200.
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 11:
If we divide 300 by 170, we get 1 and a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 535467.311
Subtract 170 from 300 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 535467.311 with a remainder of 0.013.
