We're dividing 86680 by 53 
We want to divide 86680 by 53.

Moving on to step 1:
The number 53 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.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 53

Step 2:
53 can be fit into 86 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
If we take 53 away from 86, we end up with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 53

On to step 3:
336 divided by 53 is 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 318 away from 336, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 53

On to step 4:
53 can be fit into 188 3 times, resulting in a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 163.0
Subtracting 159 from 188 leaves us with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 53

Going ahead to step 5:
290 divided by 53 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1635.0
Deduct 265 from 290 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 6:
53 goes into 250 4 times with a remainder of 38.
The next digit of our result is 4. 
Result so far: 1635.4
Subtract 212 from 250 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
When dividing 380 by 53, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1635.47
Subtract 371 from 380 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
The number 53 fits into 90 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1635.471
If we subtract 53 from 90, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
370 divided by 53 is 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 1635.4716
Subtract 318 from 370 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
520 divided by 53 is 9 with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 1635.47169
If we take 477 away from 520, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
If we divide 430 by 53, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1635.471698
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
60 divided by 53 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1635.4716981
Deduct 53 from 60 and we're left 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.

Going ahead to step 13:
When dividing 70 by 53, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1635.47169811
Deduct 53 from 70 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 1635.47169811, with a leftover of 1.7e-08.
