54243802 ÷ 388 
Let's see how many times 388 fits into 54243802.

Step 1:
388 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 388

On to step 2:
When dividing 54 by 388, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 388

Going ahead to step 3:
542 divided by 388 is 1 with a remainder of 154.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 388 from 542, we get 154.
Take the next digit (4) from the dividend and append it to 154, then repeat: 1544 / 388

Step 4:
1544 divided by 388 is 3 with a remainder of 380.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1164 from 1544 and we're left with 380.
Grab the next digit (3) from the dividend, add it to 380, then carry on: 3803 / 388

Step 5:
3803 divided by 388 is 9 with a remainder of 311.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we take 3492 away from 3803, we end up with 311.
Bring next digit (8) of the dividend behind the 311 and repeat the process: 3118 / 388

Advancing to step 6:
If we divide 3118 by 388, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 1398.0
The remainder is 14 after subtracting 3104 from 3118.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 388

Let's proceed to step 7:
The number 388 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 13980.0
Deduct 0 from 140 and we're left with 140.
Include the next digit (2) from the dividend after 140, then repeat: 1402 / 388

Advancing to step 8:
388 can be fit into 1402 3 times, resulting in a remainder of 238.
The next digit of our result is 3. 
Result so far: 139803.0
Deduct 1164 from 1402 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 9:
If we divide 2380 by 388, we get 6 and a remainder of 52.
The next digit of our result is 6. 
Result so far: 139803.6
Subtracting 2328 from 2380 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 388 is 1 with a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 139803.61
Subtracting 388 from 520 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
388 can be fit into 1320 3 times, resulting in a remainder of 156.
The next digit of our result is 3. 
Result so far: 139803.613
Subtract 1164 from 1320 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 12:
388 goes into 1560 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 139803.6134
Subtract 1552 from 1560 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 388 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 139803.6134
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
The number 388 fits into 800 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 139803.613402
The remainder is 24 after subtracting 776 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
388 goes into 240 0 times with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 139803.613402
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
If we divide 2400 by 388, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 139803.61340206
The remainder is 72 after subtracting 2328 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 139803.61340206 with a remaining 7.2e-08.
