143112 divided by 39 
We want to figure out the number of times 143112 can be divided by 39.

Advancing to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 39

Moving on to step 2:
The number 39 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 39

Moving on to step 3:
The number 39 fits into 143 3 times, leaving a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 117 from 143, we get 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 39

On to step 4:
If we divide 261 by 39, we get 6 and a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 234 from 261 leaves us with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 39

Let's proceed to step 5:
271 divided by 39 is 6 with a remainder of 37.
The next digit of our result is 6. 
Result so far: 366.0
Deduct 234 from 271 and we're left with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 39

Step 6:
When dividing 372 by 39, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 3669.0
If we subtract 351 from 372, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3669.5
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
39 goes into 150 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3669.53
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
When dividing 330 by 39, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 3669.538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 39 fits into 180 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3669.5384
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
When dividing 240 by 39, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 3669.53846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
60 divided by 39 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 3669.538461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
If we divide 210 by 39, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3669.5384615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
The number 39 fits into 150 3 times, leaving a remainder of 33.
The next digit of our result is 3. 
Result so far: 3669.53846153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

In conclusion, the division gives 3669.53846153 with a balance of 3.3e-08.
