139515 divided by 17 
Let's see how many times 17 fits into 139515.

On to step 1:
17 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 17

Advancing to step 2:
If we divide 13 by 17, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 17

Step 3:
139 divided by 17 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 136 from 139 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 17

Advancing to step 4:
35 divided by 17 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 82.0
The remainder is 1 after subtracting 34 from 35.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 17

Let's proceed to step 5:
The number 17 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
If we take 0 away from 11, we end up with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 17

Step 6:
The number 17 fits into 115 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 8206.0
Deduct 102 from 115 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
17 can be fit into 130 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 8206.7
Subtracting 119 from 130 leaves us 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.

Let's proceed to step 8:
When dividing 110 by 17, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 8206.76
Deduct 102 from 110 and we're left 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.

Step 9:
17 goes into 80 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 8206.764
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 17, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 8206.7647
If we take 119 away from 120, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
If we divide 10 by 17, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8206.7647
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8206.764705
Subtract 85 from 100 to get 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 13:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 8206.7647058
Deduct 136 from 150 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.

On to step 14:
The number 17 fits into 140 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 8206.76470588
Deduct 136 from 140 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 8206.76470588 with a remaining 4e-09.
