We look at the division of 86424743 by 17 
We want to figure out the number of times 86424743 can be divided by 17.

On to step 1:
8 divided by 17 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 17

Moving on to step 2:
If we divide 86 by 17, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 85 from 86 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 17

Let's proceed to step 3:
14 divided by 17 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 17

Advancing to step 4:
If we divide 142 by 17, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 508.0
The remainder is 6 after subtracting 136 from 142.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 17

Let's proceed to step 5:
If we divide 64 by 17, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 5083.0
If we take 51 away from 64, we end up with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 17

Step 6:
The number 17 fits into 137 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 50838.0
Subtract 136 from 137 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 17

Going ahead to step 7:
If we divide 14 by 17, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 508380.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 17

Let's proceed to step 8:
If we divide 143 by 17, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 5083808.0
Subtracting 136 from 143 leaves us 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.

Let's proceed to step 9:
17 goes into 70 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 5083808.4
Deduct 68 from 70 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 5083808.41
Deduct 17 from 20 and we're left 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.

Step 11:
If we divide 30 by 17, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 5083808.411
Deduct 17 from 30 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.

In conclusion, the division gives 5083808.411 with a balance of 0.0013.
