We look at the division of 20845162 by 171 
We want to figure out the number of times 20845162 can be divided by 171.

Going ahead to step 1:
If we divide 2 by 171, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 171

Going ahead to step 2:
When dividing 20 by 171, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 171

Advancing to step 3:
171 goes into 208 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 171 from 208 to get 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 171

Let's proceed to step 4:
171 goes into 374 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 32 after subtracting 342 from 374.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 171

Advancing to step 5:
171 can be fit into 325 1 times, resulting in a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Deduct 171 from 325 and we're left with 154.
Grab the next digit (1) from the dividend, add it to 154, then carry on: 1541 / 171

On to step 6:
1541 divided by 171 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1219.0
If we take 1539 away from 1541, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 171

Advancing to step 7:
When dividing 26 by 171, we get 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 12190.0
If we take 0 away from 26, we end up with 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 171

Moving on to step 8:
171 goes into 262 1 times with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 121901.0
If we take 171 away from 262, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
171 goes into 910 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 121901.5
If we subtract 855 from 910, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
171 can be fit into 550 3 times, resulting in a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 121901.53
The remainder is 37 after subtracting 513 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
171 can be fit into 370 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 121901.532
If we take 342 away from 370, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
171 can be fit into 280 1 times, resulting in a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 121901.5321
Subtracting 171 from 280 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 13:
171 can be fit into 1090 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 121901.53216
Deduct 1026 from 1090 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
171 goes into 640 3 times with a remainder of 127.
The next digit of our result is 3. 
Result so far: 121901.532163
The remainder is 127 after subtracting 513 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 15:
If we divide 1270 by 171, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 121901.5321637
The remainder is 73 after subtracting 1197 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 16:
171 goes into 730 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 121901.53216374
Subtracting 684 from 730 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 121901.53216374 with a remainder of 4.6e-08.
