We look at the division of 31319436 by 390 
Our goal is to divide 31319436 by 390.

Let's proceed to step 1:
390 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 390

Let's proceed to step 2:
The number 390 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 390

Step 3:
When dividing 313 by 390, we get 0 with a remainder of 313.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 313, we end up with 313.
Grab the next digit (1) from the dividend, add it to 313, then carry on: 3131 / 390

Moving on to step 4:
If we divide 3131 by 390, we get 8 and a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 3120 from 3131 and we're left with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 390

Let's proceed to step 5:
119 divided by 390 is 0 with a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we take 0 away from 119, we end up with 119.
Append the next digit (4) from the dividend to 119 and continue with: 1194 / 390

Step 6:
1194 divided by 390 is 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 803.0
Deduct 1170 from 1194 and we're left with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 390

On to step 7:
390 goes into 243 0 times with a remainder of 243.
Put 0 as the next digit of the answer. 
Result so far: 8030.0
Deduct 0 from 243 and we're left with 243.
Append the next digit (6) from the dividend to 243 and continue with: 2436 / 390

Moving on to step 8:
When dividing 2436 by 390, we get 6 with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 80306.0
The remainder is 96 after subtracting 2340 from 2436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 9:
If we divide 960 by 390, we get 2 and a remainder of 180.
The next digit of our result is 2. 
Result so far: 80306.2
If we subtract 780 from 960, we get 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 10:
If we divide 1800 by 390, we get 4 and a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 80306.24
Subtracting 1560 from 1800 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.

Step 11:
If we divide 2400 by 390, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 80306.246
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.

Let's proceed to step 12:
390 goes into 600 1 times with a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 80306.2461
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.

Let's proceed to step 13:
390 goes into 2100 5 times with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 80306.24615
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.

Moving on to step 14:
1500 divided by 390 is 3 with a remainder of 330.
Use 3 as the next digit of our solution. 
Result so far: 80306.246153
If we subtract 1170 from 1500, we 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.

Let's proceed to step 15:
3300 divided by 390 is 8 with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 80306.2461538
If we subtract 3120 from 3300, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
390 goes into 1800 4 times with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 80306.24615384
If we subtract 1560 from 1800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 80306.24615384 with a remaining 2.4e-07.
