865969 ÷ 53 
Our goal is to divide 865969 by 53.

Going ahead to step 1:
When dividing 8 by 53, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 53

Step 2:
If we divide 86 by 53, we get 1 and 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.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 53

Advancing to step 3:
53 can be fit into 335 6 times, resulting in a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 318 from 335 to get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 53

Going ahead to step 4:
179 divided by 53 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
Deduct 159 from 179 and we're left with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 53

Moving on to step 5:
206 divided by 53 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 1633.0
If we take 159 away from 206, we end up with 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 53

On to step 6:
53 goes into 479 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 16339.0
Subtracting 477 from 479 leaves us 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.

On to step 7:
If we divide 20 by 53, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 16339.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
53 goes into 200 3 times with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 16339.03
Deduct 159 from 200 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
410 divided by 53 is 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 16339.037
The remainder is 39 after subtracting 371 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
53 goes into 390 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 16339.0377
If we take 371 away from 390, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 16339.0377, with a leftover of 0.00019.
