We're dividing 15581501 by 368 
Let's see how many times 368 fits into 15581501.

On to step 1:
If we divide 1 by 368, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 368

Going ahead to step 2:
When dividing 15 by 368, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 368

Step 3:
The number 368 fits into 155 0 times, leaving a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 155 leaves us with 155.
Include the next digit (8) from the dividend after 155, then repeat: 1558 / 368

Moving on to step 4:
368 goes into 1558 4 times with a remainder of 86.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 86 after subtracting 1472 from 1558.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 368

Advancing to step 5:
368 goes into 861 2 times with a remainder of 125.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 736 from 861 leaves us with 125.
Take the next digit (5) from the dividend and append it to 125, then repeat: 1255 / 368

Step 6:
368 can be fit into 1255 3 times, resulting in a remainder of 151.
Record the quotient 3 as the next digit in the result. 
Result so far: 423.0
Subtracting 1104 from 1255 leaves us with 151.
Include the next digit (0) from the dividend after 151, then repeat: 1510 / 368

Going ahead to step 7:
The number 368 fits into 1510 4 times, leaving a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 4234.0
Subtract 1472 from 1510 to get 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 368

Moving on to step 8:
368 goes into 381 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 42341.0
Subtracting 368 from 381 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
The number 368 fits into 130 0 times, leaving a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 42341.0
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
1300 divided by 368 is 3 with a remainder of 196.
Write down 3 as next digit of the result. 
Result so far: 42341.03
Subtract 1104 from 1300 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 11:
When dividing 1960 by 368, we get 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 42341.035
Subtract 1840 from 1960 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
368 can be fit into 1200 3 times, resulting in a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 42341.0353
The remainder is 96 after subtracting 1104 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
The number 368 fits into 960 2 times, leaving a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 42341.03532
The remainder is 224 after subtracting 736 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
If we divide 2240 by 368, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 42341.035326
Deduct 2208 from 2240 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
368 goes into 320 0 times with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 42341.035326
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 16:
3200 divided by 368 is 8 with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 42341.03532608
Subtracting 2944 from 3200 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 42341.03532608, and the remainder is 2.56e-07.
