149638 ÷ 39 
Let's see how many times 39 fits into 149638.

Step 1:
If we divide 1 by 39, we get 0 and 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.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 39

Moving on to step 2:
39 goes into 14 0 times with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 39

Moving on to step 3:
When dividing 149 by 39, we get 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 117 from 149, we get 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 39

Advancing to step 4:
39 can be fit into 326 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Deduct 312 from 326 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 39

On to step 5:
39 can be fit into 143 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 383.0
If we subtract 117 from 143, we get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 39

On to step 6:
39 goes into 268 6 times with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 3836.0
The remainder is 34 after subtracting 234 from 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
When dividing 340 by 39, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 3836.8
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
When dividing 280 by 39, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 3836.87
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.

Step 9:
39 goes into 70 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 3836.871
If we take 39 away from 70, we end up with 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 10:
If we divide 310 by 39, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 3836.8717
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
370 divided by 39 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 3836.87179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
If we divide 190 by 39, we get 4 and a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 3836.871794
If we take 156 away from 190, we end up 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.

Let's proceed to step 13:
The number 39 fits into 340 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 3836.8717948
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.

Let's proceed to step 14:
When dividing 280 by 39, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 3836.87179487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 3836.87179487 and a remainder of 7e-09.
