35021288 ÷ 39 
We want to figure out the number of times 35021288 can be divided by 39.

Moving on to step 1:
If we divide 3 by 39, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 39

Moving on to step 2:
35 divided by 39 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 39

Step 3:
When dividing 350 by 39, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 312 from 350, we get 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 39

Advancing to step 4:
If we divide 382 by 39, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtract 351 from 382 to get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 39

Step 5:
If we divide 311 by 39, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 897.0
If we subtract 273 from 311, we get 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 39

Going ahead to step 6:
39 can be fit into 382 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 8979.0
Subtracting 351 from 382 leaves us with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 39

Step 7:
39 can be fit into 318 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 89798.0
If we take 312 away from 318, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 39

Let's proceed to step 8:
39 goes into 68 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 897981.0
Subtract 39 from 68 to 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 9:
290 divided by 39 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 897981.7
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.

On to step 10:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 897981.74
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.

Going ahead to step 11:
39 can be fit into 140 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 897981.743
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
39 goes into 230 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 897981.7435
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 13:
If we divide 350 by 39, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 897981.74358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
The number 39 fits into 380 9 times, leaving a remainder of 29.
The next digit of our result is 9. 
Result so far: 897981.743589
If we subtract 351 from 380, 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.

Advancing to step 15:
If we divide 290 by 39, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 897981.7435897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 16:
If we divide 170 by 39, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 897981.74358974
Deduct 156 from 170 and we're left 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 outcome is 897981.74358974, with a leftover of 1.4e-08.
