We look at the division of 672438 by 99 
We're looking to find how many times 99 goes into 672438.

Step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 99

Going ahead to step 2:
When dividing 67 by 99, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 99

Going ahead to step 3:
If we divide 672 by 99, we get 6 and a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 594 from 672 leaves us with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 99

Moving on to step 4:
When dividing 784 by 99, we get 7 with a remainder of 91.
Put 7 as the next digit of the answer. 
Result so far: 67.0
The remainder is 91 after subtracting 693 from 784.
Fetch the next digit (3) from the dividend, attach it to 91 and continue: 913 / 99

Going ahead to step 5:
The number 99 fits into 913 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 679.0
Subtracting 891 from 913 leaves us with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 99

Going ahead to step 6:
If we divide 228 by 99, we get 2 and a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 6792.0
Subtracting 198 from 228 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
When dividing 300 by 99, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 6792.3
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
If we divide 30 by 99, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 6792.3
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
300 divided by 99 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 6792.303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
When dividing 30 by 99, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6792.303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
The number 99 fits into 300 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 6792.30303
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
99 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6792.30303
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
If we divide 300 by 99, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 6792.3030303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
30 divided by 99 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 6792.3030303
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 6792.3030303, with a leftover of 3e-08.
