Let's divide 4921521 by 54
We want to divide 4921521 by 54.

Advancing to step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 54

Going ahead to step 2:
54 can be fit into 49 0 times, resulting in a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 54

Step 3:
492 divided by 54 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 486 from 492 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 54

Let's proceed to step 4:
When dividing 61 by 54, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 91.0
If we take 54 away from 61, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 54

On to step 5:
54 can be fit into 75 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 911.0
If we take 54 away from 75, we end up with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 54

Going ahead to step 6:
54 goes into 212 3 times with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 9113.0
Subtracting 162 from 212 leaves us with 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 54

Let's proceed to step 7:
54 can be fit into 501 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 91139.0
Deduct 486 from 501 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
If we divide 150 by 54, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 91139.2
Subtracting 108 from 150 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 54, we get 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 91139.27
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
54 goes into 420 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 91139.277
If we subtract 378 from 420, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 91139.277 and a remainder of 0.0042.
