79339588 ÷ 423 
Our goal is to divide 79339588 by 423.

Going ahead to step 1:
423 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 423

Going ahead to step 2:
The number 423 fits into 79 0 times, leaving 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.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 423

Going ahead to step 3:
If we divide 793 by 423, we get 1 and a remainder of 370.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 423 away from 793, we end up with 370.
Fetch the next digit (3) from the dividend, attach it to 370 and continue: 3703 / 423

Moving on to step 4:
423 can be fit into 3703 8 times, resulting in a remainder of 319.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 3384 away from 3703, we end up with 319.
Take the next digit (9) from the dividend and append it to 319, then repeat: 3199 / 423

Advancing to step 5:
When dividing 3199 by 423, we get 7 with a remainder of 238.
The next digit of our result is 7. 
Result so far: 187.0
If we subtract 2961 from 3199, we get 238.
Append the next digit (5) from the dividend to 238 and continue with: 2385 / 423

Advancing to step 6:
If we divide 2385 by 423, we get 5 and a remainder of 270.
The next digit of our result is 5. 
Result so far: 1875.0
Subtract 2115 from 2385 to get 270.
Take the next digit (8) from the dividend and append it to 270, then repeat: 2708 / 423

Moving on to step 7:
If we divide 2708 by 423, we get 6 and a remainder of 170.
The number 6 becomes the next digit in our result. 
Result so far: 18756.0
Subtract 2538 from 2708 to get 170.
Append the next digit (8) from the dividend to 170 and continue with: 1708 / 423

Advancing to step 8:
If we divide 1708 by 423, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 187564.0
Subtract 1692 from 1708 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 423 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 187564.0
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
If we divide 1600 by 423, we get 3 and a remainder of 331.
The next digit of our result is 3. 
Result so far: 187564.03
Subtracting 1269 from 1600 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 11:
The number 423 fits into 3310 7 times, leaving a remainder of 349.
The number 7 becomes the next digit in our result. 
Result so far: 187564.037
If we subtract 2961 from 3310, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 12:
The number 423 fits into 3490 8 times, leaving a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 187564.0378
Subtract 3384 from 3490 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
1060 divided by 423 is 2 with a remainder of 214.
The next digit of our result is 2. 
Result so far: 187564.03782
Subtracting 846 from 1060 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 14:
When dividing 2140 by 423, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 187564.037825
If we subtract 2115 from 2140, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 15:
The number 423 fits into 250 0 times, leaving a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 187564.037825
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 16:
423 can be fit into 2500 5 times, resulting in a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 187564.03782505
Deduct 2115 from 2500 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Our division results in 187564.03782505 with a remaining 3.85e-07.
