We're dividing 79385270 by 423 
We want to figure out the number of times 79385270 can be divided by 423.

On to step 1:
When dividing 7 by 423, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 423

Step 2:
423 goes into 79 0 times with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 423

Advancing to step 3:
If we divide 793 by 423, we get 1 and a remainder of 370.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 423 from 793 to get 370.
Take the next digit (8) from the dividend and append it to 370, then repeat: 3708 / 423

Advancing to step 4:
3708 divided by 423 is 8 with a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 3384 from 3708, we get 324.
Grab the next digit (5) from the dividend, add it to 324, then carry on: 3245 / 423

Moving on to step 5:
423 goes into 3245 7 times with a remainder of 284.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Deduct 2961 from 3245 and we're left with 284.
Include the next digit (2) from the dividend after 284, then repeat: 2842 / 423

Moving on to step 6:
The number 423 fits into 2842 6 times, leaving a remainder of 304.
Record the quotient 6 as the next digit in the result. 
Result so far: 1876.0
Subtracting 2538 from 2842 leaves us with 304.
Grab the next digit (7) from the dividend, add it to 304, then carry on: 3047 / 423

Step 7:
The number 423 fits into 3047 7 times, leaving a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 18767.0
If we subtract 2961 from 3047, we get 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 423

Going ahead to step 8:
423 can be fit into 860 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 187672.0
If we take 846 away from 860, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
423 can be fit into 140 0 times, resulting in a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 187672.0
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
The number 423 fits into 1400 3 times, leaving a remainder of 131.
The next digit of our result is 3. 
Result so far: 187672.03
If we take 1269 away from 1400, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 11:
423 can be fit into 1310 3 times, resulting in a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 187672.033
The remainder is 41 after subtracting 1269 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

In conclusion, the division gives 187672.033 with a balance of 0.0041.
