We divide 122802 by 39
Our goal is to divide 122802 by 39.

On to step 1:
39 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 39

On to step 2:
39 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 39

Going ahead to step 3:
39 goes into 122 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 117 from 122 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 39

Moving on to step 4:
If we divide 58 by 39, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 19 after subtracting 39 from 58.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 39

Advancing to step 5:
If we divide 190 by 39, we get 4 and a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 314.0
The remainder is 34 after subtracting 156 from 190.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 39

Moving on to step 6:
If we divide 342 by 39, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 3148.0
Deduct 312 from 342 and we're left 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 7:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 3148.7
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 3148.76
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
39 goes into 360 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 3148.769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
When dividing 90 by 39, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3148.7692
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
39 goes into 120 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3148.76923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3148.76923
Deduct 0 from 30 and we're left 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.

Going ahead to step 13:
39 goes into 300 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 3148.7692307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 14:
When dividing 270 by 39, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 3148.76923076
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 3148.76923076 with a remaining 3.6e-08.
