18436693 ÷ 823 
We want to figure out the number of times 18436693 can be divided by 823.

Step 1:
When dividing 1 by 823, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 823

On to step 2:
When dividing 18 by 823, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 823

Moving on to step 3:
When dividing 184 by 823, we get 0 with a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 184, we end up with 184.
Include the next digit (3) from the dividend after 184, then repeat: 1843 / 823

Moving on to step 4:
If we divide 1843 by 823, we get 2 and a remainder of 197.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1646 from 1843, we get 197.
Append the next digit (6) from the dividend to 197 and continue with: 1976 / 823

Moving on to step 5:
If we divide 1976 by 823, we get 2 and a remainder of 330.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 1646 away from 1976, we end up with 330.
Append the next digit (6) from the dividend to 330 and continue with: 3306 / 823

Moving on to step 6:
823 goes into 3306 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Deduct 3292 from 3306 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 823

On to step 7:
149 divided by 823 is 0 with a remainder of 149.
Record the quotient 0 as the next digit in the result. 
Result so far: 2240.0
The remainder is 149 after subtracting 0 from 149.
Append the next digit (3) from the dividend to 149 and continue with: 1493 / 823

Step 8:
1493 divided by 823 is 1 with a remainder of 670.
The next digit of our result is 1. 
Result so far: 22401.0
If we subtract 823 from 1493, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 9:
If we divide 6700 by 823, we get 8 and a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 22401.8
Subtract 6584 from 6700 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
The number 823 fits into 1160 1 times, leaving a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 22401.81
Subtract 823 from 1160 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 11:
When dividing 3370 by 823, we get 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 22401.814
Subtract 3292 from 3370 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 12:
When dividing 780 by 823, we get 0 with a remainder of 780.
Record the quotient 0 as the next digit in the result. 
Result so far: 22401.814
The remainder is 780 after subtracting 0 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 13:
If we divide 7800 by 823, we get 9 and a remainder of 393.
The next digit of our result is 9. 
Result so far: 22401.81409
Subtract 7407 from 7800 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 14:
823 can be fit into 3930 4 times, resulting in a remainder of 638.
Put 4 as the next digit of the answer. 
Result so far: 22401.814094
The remainder is 638 after subtracting 3292 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 15:
If we divide 6380 by 823, we get 7 and a remainder of 619.
The next digit of our result is 7. 
Result so far: 22401.8140947
The remainder is 619 after subtracting 5761 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Going ahead to step 16:
823 can be fit into 6190 7 times, resulting in a remainder of 429.
Write down 7 as next digit of the result. 
Result so far: 22401.81409477
If we take 5761 away from 6190, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

The final outcome is 22401.81409477, with a leftover of 4.29e-07.
