139624 ÷ 17 
We're looking to find how many times 17 goes into 139624.

On to step 1:
1 divided by 17 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 17

Going ahead to step 2:
The number 17 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 17

Advancing to step 3:
When dividing 139 by 17, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 3 after subtracting 136 from 139.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 17

On to step 4:
The number 17 fits into 36 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 34 from 36, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 17

Moving on to step 5:
The number 17 fits into 22 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 821.0
Subtracting 17 from 22 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 17

Advancing to step 6:
When dividing 54 by 17, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 8213.0
If we take 51 away from 54, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
17 goes into 30 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 8213.1
Subtracting 17 from 30 leaves us 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.

On to step 8:
When dividing 130 by 17, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 8213.17
If we subtract 119 from 130, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
110 divided by 17 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 8213.176
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 17, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8213.1764
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
The number 17 fits into 120 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 8213.17647
Deduct 119 from 120 and we're left 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.

Moving on to step 12:
If we divide 10 by 17, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8213.17647
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
When dividing 100 by 17, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 8213.1764705
If we subtract 85 from 100, we 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.

Advancing to step 14:
When dividing 150 by 17, we get 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 8213.17647058
Subtracting 136 from 150 leaves us 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.

The final outcome is 8213.17647058, with a leftover of 1.4e-08.
