We divide 54570899 by 396
We want to figure out the number of times 54570899 can be divided by 396.

Step 1:
The number 396 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.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 396

On to step 2:
396 can be fit into 54 0 times, resulting in a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 396

Let's proceed to step 3:
545 divided by 396 is 1 with a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 396 from 545, we get 149.
Take the next digit (7) from the dividend and append it to 149, then repeat: 1497 / 396

Moving on to step 4:
If we divide 1497 by 396, we get 3 and a remainder of 309.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1188 from 1497 leaves us with 309.
Take the next digit (0) from the dividend and append it to 309, then repeat: 3090 / 396

Advancing to step 5:
396 can be fit into 3090 7 times, resulting in a remainder of 318.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 2772 from 3090 and we're left with 318.
Take the next digit (8) from the dividend and append it to 318, then repeat: 3188 / 396

Going ahead to step 6:
396 can be fit into 3188 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 1378.0
Deduct 3168 from 3188 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 396

Advancing to step 7:
209 divided by 396 is 0 with a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 13780.0
Subtracting 0 from 209 leaves us with 209.
Bring next digit (9) of the dividend behind the 209 and repeat the process: 2099 / 396

Advancing to step 8:
The number 396 fits into 2099 5 times, leaving a remainder of 119.
The number 5 becomes the next digit in our result. 
Result so far: 137805.0
The remainder is 119 after subtracting 1980 from 2099.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
396 can be fit into 1190 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 137805.3
Subtract 1188 from 1190 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
396 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 137805.3
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
396 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 137805.3
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 137805.3, with a leftover of 0.02.
