Let's divide 619690 by 21
We want to figure out the number of times 619690 can be divided by 21.

Step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 21

Going ahead to step 2:
21 goes into 61 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 42 from 61 to get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 21

On to step 3:
21 goes into 199 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 189 from 199 and we're left with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 21

Moving on to step 4:
21 goes into 106 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
Deduct 105 from 106 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 21

Moving on to step 5:
The number 21 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 2950.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 21

Moving on to step 6:
If we divide 190 by 21, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 29509.0
Subtracting 189 from 190 leaves us 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.

Let's proceed to step 7:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 29509.0
If we take 0 away from 10, we end up 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.

Moving on to step 8:
When dividing 100 by 21, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 29509.04
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 29509.047
Subtract 147 from 160 to 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.

Let's proceed to step 10:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 29509.0476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 29509.04761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
When dividing 190 by 21, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 29509.047619
Subtracting 189 from 190 leaves us 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.

Let's proceed to step 13:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 29509.047619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 29509.04761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 29509.04761904, and the remainder is 1.6e-08.
