We divide 138884 by 39
We want to divide 138884 by 39.

Step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 39

Moving on to step 2:
When dividing 13 by 39, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 39

Going ahead to step 3:
The number 39 fits into 138 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 117 from 138 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 39

Going ahead to step 4:
39 can be fit into 218 5 times, resulting in a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 23 after subtracting 195 from 218.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 39

Advancing to step 5:
If we divide 238 by 39, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 356.0
Subtract 234 from 238 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 39

Going ahead to step 6:
The number 39 fits into 44 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 3561.0
If we take 39 away from 44, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
39 can be fit into 50 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 3561.1
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
When dividing 110 by 39, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 3561.12
Subtracting 78 from 110 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
39 goes into 320 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3561.128
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
If we divide 80 by 39, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 3561.1282
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
39 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3561.1282
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
39 can be fit into 200 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3561.128205
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
If we divide 50 by 39, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 3561.1282051
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
39 goes into 110 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 3561.12820512
Subtracting 78 from 110 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 3561.12820512, with a leftover of 3.2e-08.
