We look at the division of 68121202 by 39 
We want to divide 68121202 by 39.

Going ahead to step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 39

Advancing to step 2:
If we divide 68 by 39, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 68, we end up with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 39

Advancing to step 3:
If we divide 291 by 39, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 273 from 291 to get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 39

Let's proceed to step 4:
39 goes into 182 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
If we subtract 156 from 182, we get 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 39

On to step 5:
39 can be fit into 261 6 times, resulting in a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 1746.0
Deduct 234 from 261 and we're left with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 39

Step 6:
39 can be fit into 272 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 17466.0
If we subtract 234 from 272, we get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 39

Going ahead to step 7:
380 divided by 39 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 174669.0
The remainder is 29 after subtracting 351 from 380.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 39

Step 8:
When dividing 292 by 39, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 1746697.0
Deduct 273 from 292 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
190 divided by 39 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1746697.4
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
340 divided by 39 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 1746697.48
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
39 can be fit into 280 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 1746697.487
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
If we divide 70 by 39, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1746697.4871
If we subtract 39 from 70, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
39 goes into 310 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 1746697.48717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
370 divided by 39 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1746697.487179
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 15:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1746697.4871794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 16:
If we divide 340 by 39, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 1746697.48717948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 1746697.48717948 with a balance of 2.8e-08.
