21829088 ÷ 423 
We're looking to find how many times 423 goes into 21829088.

Let's proceed to step 1:
2 divided by 423 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 423

Step 2:
423 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 423

Step 3:
The number 423 fits into 218 0 times, leaving a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Append the next digit (2) from the dividend to 218 and continue with: 2182 / 423

Let's proceed to step 4:
423 can be fit into 2182 5 times, resulting in a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 2115 away from 2182, we end up with 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 423

Advancing to step 5:
423 goes into 679 1 times with a remainder of 256.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 423 from 679, we get 256.
Append the next digit (0) from the dividend to 256 and continue with: 2560 / 423

Let's proceed to step 6:
When dividing 2560 by 423, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 516.0
Deduct 2538 from 2560 and we're left with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 423

Advancing to step 7:
If we divide 228 by 423, we get 0 and a remainder of 228.
The number 0 becomes the next digit in our result. 
Result so far: 5160.0
If we subtract 0 from 228, we get 228.
Take the next digit (8) from the dividend and append it to 228, then repeat: 2288 / 423

On to step 8:
When dividing 2288 by 423, we get 5 with a remainder of 173.
Record the quotient 5 as the next digit in the result. 
Result so far: 51605.0
Subtracting 2115 from 2288 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 9:
423 can be fit into 1730 4 times, resulting in a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 51605.4
If we take 1692 away from 1730, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
If we divide 380 by 423, we get 0 and a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 51605.4
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 11:
423 goes into 3800 8 times with a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 51605.408
The remainder is 416 after subtracting 3384 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 12:
4160 divided by 423 is 9 with a remainder of 353.
Write down 9 as next digit of the result. 
Result so far: 51605.4089
If we take 3807 away from 4160, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 13:
3530 divided by 423 is 8 with a remainder of 146.
Use 8 as the next digit of our solution. 
Result so far: 51605.40898
Deduct 3384 from 3530 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 14:
If we divide 1460 by 423, we get 3 and a remainder of 191.
Record the quotient 3 as the next digit in the result. 
Result so far: 51605.408983
If we take 1269 away from 1460, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 15:
423 can be fit into 1910 4 times, resulting in a remainder of 218.
The next digit of our result is 4. 
Result so far: 51605.4089834
If we take 1692 away from 1910, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 16:
If we divide 2180 by 423, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 51605.40898345
If we subtract 2115 from 2180, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 51605.40898345 and a remainder of 6.5e-08.
