20315374 divided by 165 
Our goal is to divide 20315374 by 165.

On to step 1:
2 divided by 165 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 165

Moving on to step 2:
When dividing 20 by 165, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 165

Step 3:
If we divide 203 by 165, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 165 from 203 leaves us with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 165

On to step 4:
381 divided by 165 is 2 with a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 330 away from 381, we end up with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 165

Moving on to step 5:
When dividing 515 by 165, we get 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 123.0
Deduct 495 from 515 and we're left with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 165

Moving on to step 6:
If we divide 203 by 165, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1231.0
The remainder is 38 after subtracting 165 from 203.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 165

Step 7:
387 divided by 165 is 2 with a remainder of 57.
The next digit of our result is 2. 
Result so far: 12312.0
Subtracting 330 from 387 leaves us with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 165

On to step 8:
574 divided by 165 is 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 123123.0
If we subtract 495 from 574, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
165 goes into 790 4 times with a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 123123.4
Deduct 660 from 790 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
The number 165 fits into 1300 7 times, leaving a remainder of 145.
The next digit of our result is 7. 
Result so far: 123123.47
If we take 1155 away from 1300, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 11:
If we divide 1450 by 165, we get 8 and a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 123123.478
The remainder is 130 after subtracting 1320 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
165 can be fit into 1300 7 times, resulting in a remainder of 145.
Write down 7 as next digit of the result. 
Result so far: 123123.4787
If we subtract 1155 from 1300, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 13:
If we divide 1450 by 165, we get 8 and a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 123123.47878
Deduct 1320 from 1450 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
1300 divided by 165 is 7 with a remainder of 145.
Write down 7 as next digit of the result. 
Result so far: 123123.478787
If we subtract 1155 from 1300, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 15:
1450 divided by 165 is 8 with a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 123123.4787878
Deduct 1320 from 1450 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
1300 divided by 165 is 7 with a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 123123.47878787
If we subtract 1155 from 1300, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

After the division, we end up with 123123.47878787 and a remainder of 1.45e-07.
