We look at the division of 84905404 by 390 
We want to figure out the number of times 84905404 can be divided by 390.

On to step 1:
390 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 390

Let's proceed to step 2:
390 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Append the next digit (9) from the dividend to 84 and continue with: 849 / 390

Step 3:
849 divided by 390 is 2 with a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 780 away from 849, we end up with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 390

Moving on to step 4:
When dividing 690 by 390, we get 1 with a remainder of 300.
The next digit of our result is 1. 
Result so far: 21.0
If we take 390 away from 690, we end up with 300.
Fetch the next digit (5) from the dividend, attach it to 300 and continue: 3005 / 390

On to step 5:
If we divide 3005 by 390, we get 7 and a remainder of 275.
Put 7 as the next digit of the answer. 
Result so far: 217.0
Subtracting 2730 from 3005 leaves us with 275.
Append the next digit (4) from the dividend to 275 and continue with: 2754 / 390

Advancing to step 6:
390 goes into 2754 7 times with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 2177.0
The remainder is 24 after subtracting 2730 from 2754.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 390

Advancing to step 7:
390 can be fit into 240 0 times, resulting in a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 21770.0
The remainder is 240 after subtracting 0 from 240.
Append the next digit (4) from the dividend to 240 and continue with: 2404 / 390

Advancing to step 8:
2404 divided by 390 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 217706.0
If we subtract 2340 from 2404, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
The number 390 fits into 640 1 times, leaving a remainder of 250.
Put 1 as the next digit of the answer. 
Result so far: 217706.1
Subtract 390 from 640 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
2500 divided by 390 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 217706.16
The remainder is 160 after subtracting 2340 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
If we divide 1600 by 390, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 217706.164
Subtracting 1560 from 1600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 390, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 217706.1641
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
390 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 217706.1641
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
If we divide 1000 by 390, we get 2 and a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 217706.164102
If we take 780 away from 1000, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
390 goes into 2200 5 times with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 217706.1641025
Deduct 1950 from 2200 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 16:
The number 390 fits into 2500 6 times, leaving a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 217706.16410256
Deduct 2340 from 2500 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.

In conclusion, the division gives 217706.16410256 with a balance of 1.6e-07.
