Let's divide 146851 by 21
Our goal is to divide 146851 by 21.

Let's proceed to step 1:
1 divided by 21 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 21

Advancing 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
If we take 0 away from 14, we end up with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 21

Moving on to step 3:
When dividing 146 by 21, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 126 from 146 and we're left with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 21

Let's proceed to step 4:
21 goes into 208 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we subtract 189 from 208, we get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 21

Step 5:
The number 21 fits into 195 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 699.0
If we take 189 away from 195, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 21

Let's proceed to step 6:
The number 21 fits into 61 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 6992.0
If we take 42 away from 61, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 21 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 6992.9
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 6992.9
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 6992.904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 6992.9047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
130 divided by 21 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 6992.90476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 6992.904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 6992.9047619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 6992.9047619
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 6992.9047619 with a remainder of 1e-08.
