We're dividing 35359079 by 423 
We want to figure out the number of times 35359079 can be divided by 423.

Advancing to step 1:
423 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 423

Going ahead to step 2:
When dividing 35 by 423, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 423

Moving on to step 3:
423 can be fit into 353 0 times, resulting in a remainder of 353.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 353 and we're left with 353.
Append the next digit (5) from the dividend to 353 and continue with: 3535 / 423

Moving on to step 4:
When dividing 3535 by 423, we get 8 with a remainder of 151.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 3384 from 3535 leaves us with 151.
Grab the next digit (9) from the dividend, add it to 151, then carry on: 1519 / 423

Moving on to step 5:
The number 423 fits into 1519 3 times, leaving a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 1269 away from 1519, we end up with 250.
Fetch the next digit (0) from the dividend, attach it to 250 and continue: 2500 / 423

Advancing to step 6:
2500 divided by 423 is 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 835.0
Subtracting 2115 from 2500 leaves us with 385.
Bring next digit (7) of the dividend behind the 385 and repeat the process: 3857 / 423

Step 7:
423 goes into 3857 9 times with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 8359.0
Subtracting 3807 from 3857 leaves us with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 423

Let's proceed to step 8:
423 can be fit into 509 1 times, resulting in a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 83591.0
The remainder is 86 after subtracting 423 from 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 9:
860 divided by 423 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 83591.2
The remainder is 14 after subtracting 846 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
423 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 83591.2
Deduct 0 from 140 and we're left 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.

On to step 11:
423 can be fit into 1400 3 times, resulting in a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 83591.203
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.

Going ahead to step 12:
423 goes into 1310 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 83591.2033
If we take 1269 away from 1310, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 83591.2033, with a leftover of 0.00041.
