We look at the division of 79950373 by 423 
We want to divide 79950373 by 423.

Advancing to step 1:
423 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 423

On to step 2:
423 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 423

Advancing to step 3:
423 can be fit into 799 1 times, resulting in a remainder of 376.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 423 from 799 leaves us with 376.
Append the next digit (5) from the dividend to 376 and continue with: 3765 / 423

Going ahead to step 4:
423 goes into 3765 8 times with a remainder of 381.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 3384 from 3765 and we're left with 381.
Fetch the next digit (0) from the dividend, attach it to 381 and continue: 3810 / 423

Going ahead to step 5:
423 goes into 3810 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 189.0
Subtract 3807 from 3810 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 423

Step 6:
When dividing 33 by 423, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 1890.0
If we take 0 away from 33, we end up with 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 423

Let's proceed to step 7:
When dividing 337 by 423, we get 0 with a remainder of 337.
Write down 0 as next digit of the result. 
Result so far: 18900.0
If we subtract 0 from 337, we get 337.
Take the next digit (3) from the dividend and append it to 337, then repeat: 3373 / 423

Let's proceed to step 8:
3373 divided by 423 is 7 with a remainder of 412.
The number 7 becomes the next digit in our result. 
Result so far: 189007.0
If we subtract 2961 from 3373, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 9:
The number 423 fits into 4120 9 times, leaving a remainder of 313.
Write down 9 as next digit of the result. 
Result so far: 189007.9
Subtracting 3807 from 4120 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 10:
If we divide 3130 by 423, we get 7 and a remainder of 169.
Write down 7 as next digit of the result. 
Result so far: 189007.97
The remainder is 169 after subtracting 2961 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 11:
If we divide 1690 by 423, we get 3 and a remainder of 421.
The number 3 becomes the next digit in our result. 
Result so far: 189007.973
If we subtract 1269 from 1690, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 12:
If we divide 4210 by 423, we get 9 and a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 189007.9739
Deduct 3807 from 4210 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Advancing to step 13:
When dividing 4030 by 423, we get 9 with a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 189007.97399
If we subtract 3807 from 4030, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

After the division, we end up with 189007.97399 and a remainder of 0.000223.
