We divide 145368 by 21
Our goal is to divide 145368 by 21.

On to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 21

Moving on to step 2:
The number 21 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 21

On to step 3:
145 divided by 21 is 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 126 from 145 leaves us with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 21

Let's proceed to step 4:
193 divided by 21 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
The remainder is 4 after subtracting 189 from 193.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 21

Let's proceed to step 5:
21 can be fit into 46 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 692.0
If we subtract 42 from 46, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 21

Advancing to step 6:
48 divided by 21 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 6922.0
Subtract 42 from 48 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 6922.2
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6922.28
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6922.285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 6922.2857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 6922.28571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
90 divided by 21 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 6922.285714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 21 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 6922.2857142
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6922.28571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 6922.28571428, with a leftover of 1.2e-08.
