We divide 83246721 by 390
We want to figure out the number of times 83246721 can be divided by 390.

Step 1:
390 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 390

Step 2:
If we divide 83 by 390, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (2) from the dividend, attach it to 83 and continue: 832 / 390

Moving on to step 3:
The number 390 fits into 832 2 times, leaving a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 780 from 832 leaves us with 52.
Take the next digit (4) from the dividend and append it to 52, then repeat: 524 / 390

Let's proceed to step 4:
When dividing 524 by 390, we get 1 with a remainder of 134.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 390 from 524, we get 134.
Append the next digit (6) from the dividend to 134 and continue with: 1346 / 390

Advancing to step 5:
When dividing 1346 by 390, we get 3 with a remainder of 176.
Write down 3 as next digit of the result. 
Result so far: 213.0
The remainder is 176 after subtracting 1170 from 1346.
Append the next digit (7) from the dividend to 176 and continue with: 1767 / 390

On to step 6:
If we divide 1767 by 390, we get 4 and a remainder of 207.
Use 4 as the next digit of our solution. 
Result so far: 2134.0
If we subtract 1560 from 1767, we get 207.
Append the next digit (2) from the dividend to 207 and continue with: 2072 / 390

Moving on to step 7:
If we divide 2072 by 390, we get 5 and a remainder of 122.
The next digit of our result is 5. 
Result so far: 21345.0
The remainder is 122 after subtracting 1950 from 2072.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 390

Step 8:
1221 divided by 390 is 3 with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 213453.0
Deduct 1170 from 1221 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
The number 390 fits into 510 1 times, leaving a remainder of 120.
The next digit of our result is 1. 
Result so far: 213453.1
If we subtract 390 from 510, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
If we divide 1200 by 390, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 213453.13
If we subtract 1170 from 1200, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
390 can be fit into 300 0 times, resulting in a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 213453.13
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
The number 390 fits into 3000 7 times, leaving a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 213453.1307
Subtract 2730 from 3000 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 13:
2700 divided by 390 is 6 with a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 213453.13076
The remainder is 360 after subtracting 2340 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
390 can be fit into 3600 9 times, resulting in a remainder of 90.
Record the quotient 9 as the next digit in the result. 
Result so far: 213453.130769
If we subtract 3510 from 3600, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 15:
390 goes into 900 2 times with a remainder of 120.
The next digit of our result is 2. 
Result so far: 213453.1307692
The remainder is 120 after subtracting 780 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
390 goes into 1200 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 213453.13076923
Subtracting 1170 from 1200 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 213453.13076923, and the remainder is 3e-08.
