Subtract 388 from 615 to get 227.
Fetch the next digit (3) from the dividend, attach it to 227 and continue: 2273 / 388

Step 4:
388 goes into 2273 5 times with a remainder of 333.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 1940 from 2273, we get 333.
Grab the next digit (1) from the dividend, add it to 333, then carry on: 3331 / 388

Advancing to step 5:
388 goes into 3331 8 times with a remainder of 227.
The next digit of our result is 8. 
Result so far: 158.0
The remainder is 227 after subtracting 3104 from 3331.
Take the next digit (4) from the dividend and append it to 227, then repeat: 2274 / 388

Step 6:
The number 388 fits into 2274 5 times, leaving a remainder of 334.
Record the quotient 5 as the next digit in the result. 
Result so far: 1585.0
The remainder is 334 after subtracting 1940 from 2274.
Grab the next digit (9) from the dividend, add it to 334, then carry on: 3349 / 388

On to step 7:
388 goes into 3349 8 times with a remainder of 245.
Put 8 as the next digit of the answer. 
Result so far: 15858.0
Deduct 3104 from 3349 and we're left with 245.
Append the next digit (2) from the dividend to 245 and continue with: 2452 / 388

Let's proceed to step 8:
2452 divided by 388 is 6 with a remainder of 124.
The next digit of our result is 6. 
Result so far: 158586.0
If we subtract 2328 from 2452, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 9:
When dividing 1240 by 388, we get 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 158586.3
The remainder is 76 after subtracting 1164 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
If we divide 760 by 388, we get 1 and a remainder of 372.
Write down 1 as next digit of the result. 
Result so far: 158586.31
The remainder is 372 after subtracting 388 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 11:
If we divide 3720 by 388, we get 9 and a remainder of 228.
The next digit of our result is 9. 
Result so far: 158586.319
Subtract 3492 from 3720 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 12:
If we divide 2280 by 388, we get 5 and a remainder of 340.
Record the quotient 5 as the next digit in the result. 
Result so far: 158586.3195
Subtracting 1940 from 2280 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
When dividing 3400 by 388, we get 8 with a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 158586.31958
Subtracting 3104 from 3400 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 14:
2960 divided by 388 is 7 with a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 158586.319587
The remainder is 244 after subtracting 2716 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 15:
388 can be fit into 2440 6 times, resulting in a remainder of 112.
The next digit of our result is 6. 
Result so far: 158586.3195876
If we subtract 2328 from 2440, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
388 goes into 1120 2 times with a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 158586.31958762
If we subtract 776 from 1120, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The quotient of the division is 158586.31958762, and the remainder is 3.44e-07.
