We're dividing 686074 by 54 
Let's see how many times 54 fits into 686074.

On to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 54

Moving on to step 2:
68 divided by 54 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 54 from 68 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 54

On to step 3:
If we divide 146 by 54, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 38 after subtracting 108 from 146.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 54

Going ahead to step 4:
380 divided by 54 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Deduct 378 from 380 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 54

Going ahead to step 5:
54 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 1270.0
If we subtract 0 from 27, we get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 54

Advancing to step 6:
When dividing 274 by 54, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 12705.0
The remainder is 4 after subtracting 270 from 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
54 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12705.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
54 goes into 400 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 12705.07
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
When dividing 220 by 54, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 12705.074
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 54 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 12705.074
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 54 is 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 12705.07407
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
220 divided by 54 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 12705.074074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
When dividing 40 by 54, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 12705.074074
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
If we divide 400 by 54, we get 7 and a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 12705.07407407
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 12705.07407407 with a remainder of 2.2e-08.
