122762 divided by 39 
We want to divide 122762 by 39.

Moving on to step 1:
If we divide 1 by 39, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 39

Moving on to step 2:
39 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 39

Going ahead to step 3:
The number 39 fits into 122 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 117 from 122 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 39

Advancing to step 4:
39 can be fit into 57 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 39 from 57 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 39

Advancing to step 5:
If we divide 186 by 39, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 314.0
If we subtract 156 from 186, we get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 39

Going ahead to step 6:
When dividing 302 by 39, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 3147.0
If we subtract 273 from 302, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
39 goes into 290 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 3147.7
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
39 goes into 170 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3147.74
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
When dividing 140 by 39, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3147.743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
When dividing 230 by 39, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 3147.7435
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
The number 39 fits into 350 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 3147.74358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 3147.743589
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 3147.7435897
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
170 divided by 39 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 3147.74358974
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 3147.74358974 with a remainder of 1.4e-08.
