We look at the division of 90623464 by 390 
We want to divide 90623464 by 390.

Going ahead to step 1:
9 divided by 390 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 390

Going ahead to step 2:
When dividing 90 by 390, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 390

Let's proceed to step 3:
The number 390 fits into 906 2 times, leaving a remainder of 126.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 780 from 906, we get 126.
Take the next digit (2) from the dividend and append it to 126, then repeat: 1262 / 390

Step 4:
The number 390 fits into 1262 3 times, leaving a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 1170 away from 1262, we end up with 92.
Append the next digit (3) from the dividend to 92 and continue with: 923 / 390

Moving on to step 5:
923 divided by 390 is 2 with a remainder of 143.
Put 2 as the next digit of the answer. 
Result so far: 232.0
Subtracting 780 from 923 leaves us with 143.
Include the next digit (4) from the dividend after 143, then repeat: 1434 / 390

Going ahead to step 6:
When dividing 1434 by 390, we get 3 with a remainder of 264.
The number 3 becomes the next digit in our result. 
Result so far: 2323.0
The remainder is 264 after subtracting 1170 from 1434.
Include the next digit (6) from the dividend after 264, then repeat: 2646 / 390

On to step 7:
If we divide 2646 by 390, we get 6 and a remainder of 306.
Use 6 as the next digit of our solution. 
Result so far: 23236.0
Subtract 2340 from 2646 to get 306.
Append the next digit (4) from the dividend to 306 and continue with: 3064 / 390

On to step 8:
When dividing 3064 by 390, we get 7 with a remainder of 334.
Use 7 as the next digit of our solution. 
Result so far: 232367.0
Deduct 2730 from 3064 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 9:
3340 divided by 390 is 8 with a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 232367.8
The remainder is 220 after subtracting 3120 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
390 goes into 2200 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 232367.85
Subtracting 1950 from 2200 leaves us 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.

On to step 11:
The number 390 fits into 2500 6 times, leaving a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 232367.856
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.

Step 12:
When dividing 1600 by 390, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 232367.8564
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
390 goes into 400 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 232367.85641
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 390 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 232367.85641
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.

On to step 15:
When dividing 1000 by 390, we get 2 with a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 232367.8564102
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.

On to step 16:
390 goes into 2200 5 times with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 232367.85641025
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.

After the division, we end up with 232367.85641025 and a remainder of 2.5e-07.
