Let's divide 20219255 by 390
We want to divide 20219255 by 390.

Let's proceed to step 1:
390 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 390

On to step 2:
The number 390 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 390

Step 3:
390 can be fit into 202 0 times, resulting in a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 202 to get 202.
Bring next digit (1) of the dividend behind the 202 and repeat the process: 2021 / 390

On to step 4:
The number 390 fits into 2021 5 times, leaving a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 1950 from 2021 and we're left with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 390

Step 5:
390 goes into 719 1 times with a remainder of 329.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 390 from 719 to get 329.
Bring next digit (2) of the dividend behind the 329 and repeat the process: 3292 / 390

Let's proceed to step 6:
When dividing 3292 by 390, we get 8 with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 518.0
If we take 3120 away from 3292, we end up with 172.
Grab the next digit (5) from the dividend, add it to 172, then carry on: 1725 / 390

Step 7:
390 goes into 1725 4 times with a remainder of 165.
Write down 4 as next digit of the result. 
Result so far: 5184.0
If we take 1560 away from 1725, we end up with 165.
Take the next digit (5) from the dividend and append it to 165, then repeat: 1655 / 390

Advancing to step 8:
When dividing 1655 by 390, we get 4 with a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 51844.0
Subtract 1560 from 1655 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
The number 390 fits into 950 2 times, leaving a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 51844.2
If we take 780 away from 950, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
The number 390 fits into 1700 4 times, leaving a remainder of 140.
The next digit of our result is 4. 
Result so far: 51844.24
If we take 1560 away from 1700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
The number 390 fits into 1400 3 times, leaving a remainder of 230.
The next digit of our result is 3. 
Result so far: 51844.243
Deduct 1170 from 1400 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
The number 390 fits into 2300 5 times, leaving a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 51844.2435
The remainder is 350 after subtracting 1950 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
390 can be fit into 3500 8 times, resulting in a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 51844.24358
Subtracting 3120 from 3500 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 14:
390 can be fit into 3800 9 times, resulting in a remainder of 290.
Put 9 as the next digit of the answer. 
Result so far: 51844.243589
If we take 3510 away from 3800, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 15:
The number 390 fits into 2900 7 times, leaving a remainder of 170.
Put 7 as the next digit of the answer. 
Result so far: 51844.2435897
Subtract 2730 from 2900 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 16:
390 goes into 1700 4 times with a remainder of 140.
The next digit of our result is 4. 
Result so far: 51844.24358974
Subtract 1560 from 1700 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 51844.24358974, with a leftover of 1.4e-07.
