We look at the division of 82420401 by 390 
Our goal is to divide 82420401 by 390.

Step 1:
390 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 390

Step 2:
390 can be fit into 82 0 times, resulting in a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (4) of the dividend behind the 82 and repeat the process: 824 / 390

Step 3:
824 divided by 390 is 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 780 away from 824, we end up with 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 390

On to step 4:
442 divided by 390 is 1 with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 390 from 442 and we're left with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 390

On to step 5:
390 can be fit into 520 1 times, resulting in a remainder of 130.
The next digit of our result is 1. 
Result so far: 211.0
The remainder is 130 after subtracting 390 from 520.
Fetch the next digit (4) from the dividend, attach it to 130 and continue: 1304 / 390

Let's proceed to step 6:
1304 divided by 390 is 3 with a remainder of 134.
The next digit of our result is 3. 
Result so far: 2113.0
Subtract 1170 from 1304 to get 134.
Fetch the next digit (0) from the dividend, attach it to 134 and continue: 1340 / 390

On to step 7:
390 goes into 1340 3 times with a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 21133.0
Subtract 1170 from 1340 to get 170.
Grab the next digit (1) from the dividend, add it to 170, then carry on: 1701 / 390

On to step 8:
When dividing 1701 by 390, we get 4 with a remainder of 141.
Put 4 as the next digit of the answer. 
Result so far: 211334.0
Deduct 1560 from 1701 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 9:
1410 divided by 390 is 3 with a remainder of 240.
Record the quotient 3 as the next digit in the result. 
Result so far: 211334.3
Subtracting 1170 from 1410 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
2400 divided by 390 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 211334.36
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
390 goes into 600 1 times with a remainder of 210.
The number 1 becomes the next digit in our result. 
Result so far: 211334.361
Subtracting 390 from 600 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 12:
390 goes into 2100 5 times with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 211334.3615
The remainder is 150 after subtracting 1950 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 13:
390 goes into 1500 3 times with a remainder of 330.
Use 3 as the next digit of our solution. 
Result so far: 211334.36153
Subtract 1170 from 1500 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 14:
3300 divided by 390 is 8 with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 211334.361538
If we take 3120 away from 3300, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 15:
If we divide 1800 by 390, we get 4 and a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 211334.3615384
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
When dividing 2400 by 390, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 211334.36153846
Deduct 2340 from 2400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 211334.36153846 with a remainder of 6e-08.
