Let's divide 31673736 by 390
Let's see how many times 390 fits into 31673736.

Let's proceed to step 1:
If we divide 3 by 390, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 390

Moving on to step 2:
31 divided by 390 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 390

Moving on to step 3:
390 goes into 316 0 times with a remainder of 316.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 316 and we're left with 316.
Take the next digit (7) from the dividend and append it to 316, then repeat: 3167 / 390

Moving on to step 4:
When dividing 3167 by 390, we get 8 with a remainder of 47.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 3120 from 3167 to get 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 390

Moving on to step 5:
The number 390 fits into 473 1 times, leaving a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 83 after subtracting 390 from 473.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 390

On to step 6:
The number 390 fits into 837 2 times, leaving a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 812.0
If we subtract 780 from 837, we get 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 390

Step 7:
573 divided by 390 is 1 with a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 8121.0
If we take 390 away from 573, we end up with 183.
Take the next digit (6) from the dividend and append it to 183, then repeat: 1836 / 390

Step 8:
1836 divided by 390 is 4 with a remainder of 276.
The next digit of our result is 4. 
Result so far: 81214.0
Deduct 1560 from 1836 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 9:
When dividing 2760 by 390, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 81214.7
If we take 2730 away from 2760, we end up 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.

Advancing to step 10:
300 divided by 390 is 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 81214.7
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
The number 390 fits into 3000 7 times, leaving a remainder of 270.
Use 7 as the next digit of our solution. 
Result so far: 81214.707
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.

Going ahead to step 12:
390 goes into 2700 6 times with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 81214.7076
If we subtract 2340 from 2700, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
390 goes into 3600 9 times with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 81214.70769
Subtracting 3510 from 3600 leaves us with 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 14:
390 goes into 900 2 times with a remainder of 120.
The next digit of our result is 2. 
Result so far: 81214.707692
Deduct 780 from 900 and we're left with 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 15:
When dividing 1200 by 390, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 81214.7076923
The remainder is 30 after subtracting 1170 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
390 goes into 300 0 times with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 81214.7076923
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 81214.7076923 with a remainder of 3e-07.
