We're dividing 141954 by 39 
Our goal is to divide 141954 by 39.

On to step 1:
1 divided by 39 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 39

Step 2:
If we divide 14 by 39, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 39

Step 3:
If we divide 141 by 39, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 117 from 141, we get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 39

Going ahead to step 4:
The number 39 fits into 249 6 times, leaving a remainder of 15.
The next digit of our result is 6. 
Result so far: 36.0
If we take 234 away from 249, we end up with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 39

Step 5:
When dividing 155 by 39, we get 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 363.0
If we take 117 away from 155, we end up with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 39

Going ahead to step 6:
When dividing 384 by 39, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 3639.0
Deduct 351 from 384 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.

Moving on to step 7:
If we divide 330 by 39, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 3639.8
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
When dividing 180 by 39, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 3639.84
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.

Advancing to step 9:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3639.846
Subtracting 234 from 240 leaves us with 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 10:
When dividing 60 by 39, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 3639.8461
Subtracting 39 from 60 leaves us with 21.
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 11:
210 divided by 39 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3639.84615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 39, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3639.846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
If we divide 330 by 39, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 3639.8461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3639.84615384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 3639.84615384 and a remainder of 2.4e-08.
