54645386 ÷ 299 
We want to figure out the number of times 54645386 can be divided by 299.

Advancing to step 1:
If we divide 5 by 299, we get 0 and 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.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 299

Advancing to step 2:
299 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Grab the next digit (6) from the dividend, add it to 54, then carry on: 546 / 299

Going ahead to step 3:
The number 299 fits into 546 1 times, leaving a remainder of 247.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 299 from 546 to get 247.
Grab the next digit (4) from the dividend, add it to 247, then carry on: 2474 / 299

Advancing to step 4:
299 goes into 2474 8 times with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 2392 from 2474 to get 82.
Bring next digit (5) of the dividend behind the 82 and repeat the process: 825 / 299

Let's proceed to step 5:
If we divide 825 by 299, we get 2 and a remainder of 227.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Subtracting 598 from 825 leaves us with 227.
Grab the next digit (3) from the dividend, add it to 227, then carry on: 2273 / 299

Let's proceed to step 6:
The number 299 fits into 2273 7 times, leaving a remainder of 180.
Put 7 as the next digit of the answer. 
Result so far: 1827.0
If we subtract 2093 from 2273, we get 180.
Append the next digit (8) from the dividend to 180 and continue with: 1808 / 299

Moving on to step 7:
The number 299 fits into 1808 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 18276.0
If we subtract 1794 from 1808, we get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 299

On to step 8:
299 goes into 146 0 times with a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 182760.0
Subtracting 0 from 146 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 9:
299 goes into 1460 4 times with a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 182760.4
The remainder is 264 after subtracting 1196 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 10:
299 goes into 2640 8 times with a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 182760.48
Deduct 2392 from 2640 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
299 can be fit into 2480 8 times, resulting in a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 182760.488
The remainder is 88 after subtracting 2392 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Our division results in 182760.488 with a remaining 0.0088.
