Let's divide 521974 by 54
We want to divide 521974 by 54.

On to step 1:
The number 54 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 54

Step 2:
52 divided by 54 is 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 54

Step 3:
54 goes into 521 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 35 after subtracting 486 from 521.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 54

Let's proceed to step 4:
The number 54 fits into 359 6 times, leaving a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 96.0
If we take 324 away from 359, we end up with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 54

On to step 5:
357 divided by 54 is 6 with a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 966.0
If we take 324 away from 357, we end up with 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 54

On to step 6:
The number 54 fits into 334 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 9666.0
Subtract 324 from 334 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
54 goes into 100 1 times with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 9666.1
Deduct 54 from 100 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
460 divided by 54 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 9666.18
Deduct 432 from 460 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
54 goes into 280 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9666.185
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 54, we get 1 and a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 9666.1851
If we take 54 away from 100, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
54 goes into 460 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 9666.18518
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
If we divide 280 by 54, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9666.185185
Subtract 270 from 280 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
When dividing 100 by 54, we get 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 9666.1851851
If we take 54 away from 100, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
When dividing 460 by 54, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 9666.18518518
Subtracting 432 from 460 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 9666.18518518 and a remainder of 2.8e-08.
