We divide 54266746 by 399
We're looking to find how many times 399 goes into 54266746.

Let's proceed to step 1:
The number 399 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 399

Advancing to step 2:
When dividing 54 by 399, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 399

Going ahead to step 3:
When dividing 542 by 399, we get 1 with a remainder of 143.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 399 from 542 to get 143.
Fetch the next digit (6) from the dividend, attach it to 143 and continue: 1436 / 399

Advancing to step 4:
399 goes into 1436 3 times with a remainder of 239.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1197 away from 1436, we end up with 239.
Fetch the next digit (6) from the dividend, attach it to 239 and continue: 2396 / 399

Let's proceed to step 5:
399 goes into 2396 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 136.0
Subtract 2394 from 2396 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 399

On to step 6:
399 goes into 27 0 times with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 1360.0
Subtracting 0 from 27 leaves us with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 399

Step 7:
The number 399 fits into 274 0 times, leaving a remainder of 274.
The number 0 becomes the next digit in our result. 
Result so far: 13600.0
Deduct 0 from 274 and we're left with 274.
Append the next digit (6) from the dividend to 274 and continue with: 2746 / 399

Let's proceed to step 8:
399 goes into 2746 6 times with a remainder of 352.
The next digit of our result is 6. 
Result so far: 136006.0
Subtracting 2394 from 2746 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 9:
399 can be fit into 3520 8 times, resulting in a remainder of 328.
The next digit of our result is 8. 
Result so far: 136006.8
If we subtract 3192 from 3520, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
3280 divided by 399 is 8 with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 136006.88
If we take 3192 away from 3280, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 136006.88, and the remainder is 0.088.
