We're dividing 1998040 by 672 
We want to divide 1998040 by 672.

Advancing to step 1:
1 divided by 672 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 672

Advancing to step 2:
If we divide 19 by 672, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 672

On to step 3:
672 can be fit into 199 0 times, resulting in a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 199 to get 199.
Take the next digit (8) from the dividend and append it to 199, then repeat: 1998 / 672

Let's proceed to step 4:
672 can be fit into 1998 2 times, resulting in a remainder of 654.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1344 away from 1998, we end up with 654.
Include the next digit (0) from the dividend after 654, then repeat: 6540 / 672

Going ahead to step 5:
If we divide 6540 by 672, we get 9 and a remainder of 492.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 6048 from 6540 leaves us with 492.
Bring next digit (4) of the dividend behind the 492 and repeat the process: 4924 / 672

Step 6:
672 can be fit into 4924 7 times, resulting in a remainder of 220.
Use 7 as the next digit of our solution. 
Result so far: 297.0
Subtract 4704 from 4924 to get 220.
Include the next digit (0) from the dividend after 220, then repeat: 2200 / 672

Going ahead to step 7:
672 goes into 2200 3 times with a remainder of 184.
The next digit of our result is 3. 
Result so far: 2973.0
The remainder is 184 after subtracting 2016 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 8:
The number 672 fits into 1840 2 times, leaving a remainder of 496.
Put 2 as the next digit of the answer. 
Result so far: 2973.2
Subtract 1344 from 1840 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 9:
The number 672 fits into 4960 7 times, leaving a remainder of 256.
Put 7 as the next digit of the answer. 
Result so far: 2973.27
If we subtract 4704 from 4960, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 10:
672 can be fit into 2560 3 times, resulting in a remainder of 544.
Use 3 as the next digit of our solution. 
Result so far: 2973.273
Subtract 2016 from 2560 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 11:
If we divide 5440 by 672, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 2973.2738
If we subtract 5376 from 5440, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
672 can be fit into 640 0 times, resulting in a remainder of 640.
The next digit of our result is 0. 
Result so far: 2973.2738
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 13:
6400 divided by 672 is 9 with a remainder of 352.
The next digit of our result is 9. 
Result so far: 2973.273809
If we subtract 6048 from 6400, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 14:
If we divide 3520 by 672, we get 5 and a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 2973.2738095
The remainder is 160 after subtracting 3360 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
1600 divided by 672 is 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 2973.27380952
Subtract 1344 from 1600 to get 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 final outcome is 2973.27380952, with a leftover of 2.56e-07.
