86638937 ÷ 17 
We want to divide 86638937 by 17.

Step 1:
The number 17 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 17

Let's proceed 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
Subtracting 85 from 86 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 17

Moving on to step 3:
17 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 17

Going ahead to step 4:
163 divided by 17 is 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 509.0
If we subtract 153 from 163, we get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 17

Moving on to step 5:
If we divide 108 by 17, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 5096.0
Subtracting 102 from 108 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 17

Moving on to step 6:
17 can be fit into 69 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 50964.0
Subtracting 68 from 69 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 17

Moving on to step 7:
17 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 509640.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 17

Step 8:
The number 17 fits into 137 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 5096408.0
Deduct 136 from 137 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.

On to step 9:
10 divided by 17 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 5096408.0
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.

Advancing to step 10:
17 goes into 100 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5096408.05
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
17 goes into 150 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 5096408.058
Subtract 136 from 150 to get 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 12:
When dividing 140 by 17, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 5096408.0588
Subtracting 136 from 140 leaves us 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.

The quotient of the division is 5096408.0588, and the remainder is 4e-05.
