The number 388 fits into 1567 4 times, leaving a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 1552 away from 1567, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 388

Let's proceed to step 5:
388 goes into 151 0 times with a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
The remainder is 151 after subtracting 0 from 151.
Grab the next digit (9) from the dividend, add it to 151, then carry on: 1519 / 388

Advancing to step 6:
388 can be fit into 1519 3 times, resulting in a remainder of 355.
Put 3 as the next digit of the answer. 
Result so far: 1403.0
If we subtract 1164 from 1519, we get 355.
Fetch the next digit (9) from the dividend, attach it to 355 and continue: 3559 / 388

Let's proceed to step 7:
388 goes into 3559 9 times with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 14039.0
Subtracting 3492 from 3559 leaves us with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 388

Advancing to step 8:
When dividing 671 by 388, we get 1 with a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 140391.0
Subtract 388 from 671 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 9:
If we divide 2830 by 388, we get 7 and a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 140391.7
If we subtract 2716 from 2830, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 10:
The number 388 fits into 1140 2 times, leaving a remainder of 364.
The next digit of our result is 2. 
Result so far: 140391.72
Subtracting 776 from 1140 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
The number 388 fits into 3640 9 times, leaving a remainder of 148.
Use 9 as the next digit of our solution. 
Result so far: 140391.729
Subtract 3492 from 3640 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 12:
1480 divided by 388 is 3 with a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 140391.7293
If we take 1164 away from 1480, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 13:
388 can be fit into 3160 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 140391.72938
The remainder is 56 after subtracting 3104 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
388 can be fit into 560 1 times, resulting in a remainder of 172.
Write down 1 as next digit of the result. 
Result so far: 140391.729381
The remainder is 172 after subtracting 388 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 15:
388 can be fit into 1720 4 times, resulting in a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 140391.7293814
Subtracting 1552 from 1720 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 16:
388 can be fit into 1680 4 times, resulting in a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 140391.72938144
Deduct 1552 from 1680 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 140391.72938144, and the remainder is 1.28e-07.
