We're dividing 15120949 by 74 
We want to divide 15120949 by 74.

Moving on to step 1:
74 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 74

Let's proceed to step 2:
74 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 74

Moving on to step 3:
The number 74 fits into 151 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 148 from 151, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 74

Advancing to step 4:
If we divide 32 by 74, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 32, we get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 74

Let's proceed to step 5:
If we divide 320 by 74, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 204.0
The remainder is 24 after subtracting 296 from 320.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 74

Advancing to step 6:
249 divided by 74 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 2043.0
Deduct 222 from 249 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 74

Moving on to step 7:
74 can be fit into 274 3 times, resulting in a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 20433.0
Deduct 222 from 274 and we're left with 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 74

Going ahead to step 8:
The number 74 fits into 529 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 204337.0
If we take 518 away from 529, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
74 can be fit into 110 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 204337.1
Deduct 74 from 110 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
74 can be fit into 360 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 204337.14
Deduct 296 from 360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
The number 74 fits into 640 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 204337.148
Subtracting 592 from 640 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
The number 74 fits into 480 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 204337.1486
Subtract 444 from 480 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
If we divide 360 by 74, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 204337.14864
The remainder is 64 after subtracting 296 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
74 can be fit into 640 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 204337.148648
The remainder is 48 after subtracting 592 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 15:
480 divided by 74 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 204337.1486486
Subtracting 444 from 480 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
The number 74 fits into 360 4 times, leaving a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 204337.14864864
Deduct 296 from 360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 204337.14864864, with a leftover of 6.4e-08.
