We're dividing 2053021 by 170 
We want to divide 2053021 by 170.

Moving on to step 1:
The number 170 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 170

Let's proceed to step 2:
170 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 170

Going ahead to step 3:
If we divide 205 by 170, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 170 from 205 to get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 170

Advancing to step 4:
If we divide 353 by 170, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 13 after subtracting 340 from 353.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 170

Going ahead to step 5:
130 divided by 170 is 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
The remainder is 130 after subtracting 0 from 130.
Include the next digit (2) from the dividend after 130, then repeat: 1302 / 170

Step 6:
1302 divided by 170 is 7 with a remainder of 112.
The next digit of our result is 7. 
Result so far: 1207.0
Subtracting 1190 from 1302 leaves us with 112.
Grab the next digit (1) from the dividend, add it to 112, then carry on: 1121 / 170

Step 7:
170 goes into 1121 6 times with a remainder of 101.
Use 6 as the next digit of our solution. 
Result so far: 12076.0
If we take 1020 away from 1121, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 8:
170 goes into 1010 5 times with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 12076.5
Deduct 850 from 1010 and we're left with 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 9:
170 goes into 1600 9 times with a remainder of 70.
The next digit of our result is 9. 
Result so far: 12076.59
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.

Going ahead to step 10:
700 divided by 170 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 12076.594
Subtract 680 from 700 to 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.

Step 11:
170 can be fit into 200 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 12076.5941
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.

Step 12:
The number 170 fits into 300 1 times, leaving a remainder of 130.
The next digit of our result is 1. 
Result so far: 12076.59411
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.

The final outcome is 12076.59411, with a leftover of 0.00013.
