We're dividing 22017090 by 170 
Let's see how many times 170 fits into 22017090.

Moving on to step 1:
When dividing 2 by 170, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 170

On to step 2:
The number 170 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 170

Advancing to step 3:
170 goes into 220 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 170 from 220 leaves us with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 170

Advancing to step 4:
170 can be fit into 501 2 times, resulting in a remainder of 161.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 340 away from 501, we end up with 161.
Take the next digit (7) from the dividend and append it to 161, then repeat: 1617 / 170

Going ahead to step 5:
170 can be fit into 1617 9 times, resulting in a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we subtract 1530 from 1617, we get 87.
Include the next digit (0) from the dividend after 87, then repeat: 870 / 170

Let's proceed to step 6:
If we divide 870 by 170, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1295.0
If we subtract 850 from 870, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 170

Going ahead to step 7:
170 goes into 209 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 12951.0
The remainder is 39 after subtracting 170 from 209.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 170

Moving on to step 8:
170 can be fit into 390 2 times, resulting in a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 129512.0
Deduct 340 from 390 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 170, we get 2 and a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 129512.2
Subtract 340 from 500 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
170 can be fit into 1600 9 times, resulting in a remainder of 70.
The next digit of our result is 9. 
Result so far: 129512.29
If we take 1530 away from 1600, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
When dividing 700 by 170, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 129512.294
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
When dividing 200 by 170, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 129512.2941
If we take 170 away from 200, we end up 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.

On to step 13:
170 goes into 300 1 times with a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 129512.29411
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.

After the division, we end up with 129512.29411 and a remainder of 0.00013.
