54893930 ÷ 15 
We're looking to find how many times 15 goes into 54893930.

Step 1:
15 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 15

Step 2:
15 can be fit into 54 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 45 from 54, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 15

Let's proceed to step 3:
98 divided by 15 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 90 from 98, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 15

Let's proceed to step 4:
15 goes into 89 5 times with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 365.0
Deduct 75 from 89 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 15

On to step 5:
The number 15 fits into 143 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 3659.0
If we take 135 away from 143, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 15

Let's proceed to step 6:
89 divided by 15 is 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 36595.0
Subtract 75 from 89 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 15

On to step 7:
15 goes into 143 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 365959.0
The remainder is 8 after subtracting 135 from 143.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 15

Moving on to step 8:
The number 15 fits into 80 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 3659595.0
Subtract 75 from 80 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3659595.3
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3659595.33
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 3659595.33, with a leftover of 0.005.
