642017 divided by 86 
We're looking to find how many times 86 goes into 642017.

Moving on to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 86

On to step 2:
64 divided by 86 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 86

Let's proceed to step 3:
When dividing 642 by 86, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 602 from 642 and we're left with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 86

Moving on to step 4:
86 goes into 400 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 74.0
The remainder is 56 after subtracting 344 from 400.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 86

Moving on to step 5:
86 goes into 561 6 times with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 746.0
Deduct 516 from 561 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 86

Step 6:
86 can be fit into 457 5 times, resulting in a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 7465.0
If we take 430 away from 457, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
270 divided by 86 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 7465.3
Subtracting 258 from 270 leaves us 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.

Moving on to step 8:
If we divide 120 by 86, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 7465.31
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 7465.313
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 10:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 7465.3139
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
If we divide 460 by 86, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7465.31395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
The number 86 fits into 300 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 7465.313953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
86 goes into 420 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 7465.3139534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 7465.31395348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 7465.31395348 and a remainder of 7.2e-08.
