We look at the division of 686169 by 53 
We want to figure out the number of times 686169 can be divided by 53.

Advancing to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 53

On to step 2:
When dividing 68 by 53, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 68, we end up with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 53

On to step 3:
If we divide 156 by 53, we get 2 and a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 106 away from 156, we end up with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 53

Going ahead to step 4:
When dividing 501 by 53, we get 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 24 after subtracting 477 from 501.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 53

On to step 5:
246 divided by 53 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1294.0
Deduct 212 from 246 and we're left with 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 53

Step 6:
The number 53 fits into 349 6 times, leaving a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 12946.0
Subtract 318 from 349 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 53 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 12946.5
Subtract 265 from 310 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
When dividing 450 by 53, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 12946.58
Subtract 424 from 450 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 53 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 12946.584
Subtracting 212 from 260 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 53, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 12946.5849
If we take 477 away from 480, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
30 divided by 53 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 12946.5849
Subtracting 0 from 30 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.

On to step 12:
53 can be fit into 300 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 12946.584905
Subtract 265 from 300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
If we divide 350 by 53, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 12946.5849056
Subtracting 318 from 350 leaves us 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.

Step 14:
320 divided by 53 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 12946.58490566
Deduct 318 from 320 and we're left 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.

The final outcome is 12946.58490566, with a leftover of 2e-09.
