We're dividing 83573191 by 423 
Let's see how many times 423 fits into 83573191.

Advancing to step 1:
The number 423 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 423

Moving on to step 2:
When dividing 83 by 423, we get 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 423

Step 3:
When dividing 835 by 423, we get 1 with a remainder of 412.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 423 from 835 to get 412.
Bring next digit (7) of the dividend behind the 412 and repeat the process: 4127 / 423

Moving on to step 4:
The number 423 fits into 4127 9 times, leaving a remainder of 320.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 3807 from 4127, we get 320.
Fetch the next digit (3) from the dividend, attach it to 320 and continue: 3203 / 423

Advancing to step 5:
3203 divided by 423 is 7 with a remainder of 242.
The next digit of our result is 7. 
Result so far: 197.0
If we take 2961 away from 3203, we end up with 242.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 423

Step 6:
If we divide 2421 by 423, we get 5 and a remainder of 306.
The next digit of our result is 5. 
Result so far: 1975.0
Subtracting 2115 from 2421 leaves us with 306.
Take the next digit (9) from the dividend and append it to 306, then repeat: 3069 / 423

Moving on to step 7:
If we divide 3069 by 423, we get 7 and a remainder of 108.
Put 7 as the next digit of the answer. 
Result so far: 19757.0
Subtracting 2961 from 3069 leaves us with 108.
Fetch the next digit (1) from the dividend, attach it to 108 and continue: 1081 / 423

Step 8:
If we divide 1081 by 423, we get 2 and a remainder of 235.
Use 2 as the next digit of our solution. 
Result so far: 197572.0
Deduct 846 from 1081 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 9:
If we divide 2350 by 423, we get 5 and a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 197572.5
Subtract 2115 from 2350 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 10:
423 goes into 2350 5 times with a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 197572.55
Subtract 2115 from 2350 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

In conclusion, the division gives 197572.55 with a balance of 0.235.
