Let's divide 653639 by 86
We're looking to find how many times 86 goes into 653639.

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
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 86

On to step 2:
86 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 86

Going ahead to step 3:
86 can be fit into 653 7 times, resulting in a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 602 from 653 leaves us with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 86

Let's proceed to step 4:
86 can be fit into 516 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 76.0
If we take 516 away from 516, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 86

Advancing to step 5:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 760.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 86

Step 6:
When dividing 39 by 86, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 7600.0
If we take 0 away from 39, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
The number 86 fits into 390 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 7600.4
If we take 344 away from 390, 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.

Moving on to step 8:
86 goes into 460 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7600.45
Subtracting 430 from 460 leaves us 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.

Going ahead to step 9:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 7600.453
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 7600.4534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 7600.45348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
The number 86 fits into 720 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 7600.453488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 7600.453488, with a leftover of 3.2e-06.
