Let's divide 1939967 by 21
We want to divide 1939967 by 21.

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 subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 21

Let's proceed to step 2:
19 divided by 21 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 21

Let's proceed to step 3:
193 divided by 21 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 189 from 193 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 21

On to step 4:
21 goes into 49 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtract 42 from 49 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 21

Advancing to step 5:
If we divide 79 by 21, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 923.0
If we take 63 away from 79, we end up with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 21

Advancing to step 6:
The number 21 fits into 166 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 9237.0
Deduct 147 from 166 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 21

Step 7:
21 goes into 197 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 92379.0
Deduct 189 from 197 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 92379.3
Deduct 63 from 80 and we're left 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.

Let's proceed to step 9:
21 goes into 170 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 92379.38
Subtract 168 from 170 to get 2.
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 10:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 92379.38
If we take 0 away from 20, we end up 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 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 92379.3809
Subtracting 189 from 200 leaves us with 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 12:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 92379.38095
If we take 105 away from 110, we end up 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.

Let's proceed to step 13:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 92379.380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
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: 92379.3809523
If we take 63 away from 80, we end up 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.

Moving on to step 15:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 92379.38095238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 92379.38095238, and the remainder is 2e-09.
