We're dividing 690317 by 54 
We want to divide 690317 by 54.

Step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 54

On to step 2:
54 goes into 69 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 54 from 69 and we're left with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 54

On to step 3:
When dividing 150 by 54, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 42 after subtracting 108 from 150.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 54

Let's proceed to step 4:
54 goes into 423 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 127.0
Deduct 378 from 423 and we're left with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 54

On to step 5:
If we divide 451 by 54, we get 8 and a remainder of 19.
The next digit of our result is 8. 
Result so far: 1278.0
If we take 432 away from 451, we end up with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 54

Let's proceed to step 6:
54 goes into 197 3 times with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 12783.0
If we take 162 away from 197, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
54 goes into 350 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 12783.6
If we subtract 324 from 350, we 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.

Let's proceed to step 8:
When dividing 260 by 54, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 12783.64
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
440 divided by 54 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 12783.648
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
If we divide 80 by 54, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 12783.6481
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
54 goes into 260 4 times with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 12783.64814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
If we divide 440 by 54, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 12783.648148
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 12783.6481481
If we subtract 54 from 80, we 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.

Let's proceed to step 14:
54 goes into 260 4 times with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 12783.64814814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 12783.64814814, with a leftover of 4.4e-08.
