We're dividing 18169346 by 21 
We're looking to find how many times 21 goes into 18169346.

Going ahead to step 1:
1 divided by 21 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 21

Step 2:
If we divide 18 by 21, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 21

Let's proceed to step 3:
181 divided by 21 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 13 after subtracting 168 from 181.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 21

Advancing to step 4:
The number 21 fits into 136 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 10 after subtracting 126 from 136.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 21

Moving on to step 5:
109 divided by 21 is 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 865.0
Subtracting 105 from 109 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 21

Advancing to step 6:
If we divide 43 by 21, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 8652.0
Subtract 42 from 43 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 21

Going ahead to step 7:
When dividing 14 by 21, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 86520.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 21

Step 8:
If we divide 146 by 21, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 865206.0
Deduct 126 from 146 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 21, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 865206.9
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 865206.95
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 865206.952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 21, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 865206.9523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 865206.95238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 865206.95238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 865206.9523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 16:
21 goes into 110 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 865206.95238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 865206.95238095 with a balance of 5e-09.
