We're dividing 686443 by 54 
We want to divide 686443 by 54.

Advancing to step 1:
If we divide 6 by 54, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 54

Let's proceed to step 2:
The number 54 fits into 68 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 54 from 68, we get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 54

Step 3:
When dividing 146 by 54, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 108 from 146, we get 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 54

On to step 4:
54 goes into 384 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 127.0
If we take 378 away from 384, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 54

Step 5:
The number 54 fits into 64 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1271.0
Deduct 54 from 64 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 54

Let's proceed to step 6:
When dividing 103 by 54, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 12711.0
If we take 54 away from 103, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
If we divide 490 by 54, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 12711.9
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 54, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12711.9
If we subtract 0 from 40, we 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 9:
400 divided by 54 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 12711.907
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
The number 54 fits into 220 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 12711.9074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
40 divided by 54 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12711.9074
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.

Let's proceed to step 12:
54 goes into 400 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 12711.907407
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.

Let's proceed to step 13:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 12711.9074074
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
40 divided by 54 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12711.9074074
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.

In conclusion, the division gives 12711.9074074 with a balance of 4e-08.
