74732065 ÷ 21 
We want to figure out the number of times 74732065 can be divided by 21.

Advancing to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 21

Moving on to step 2:
21 goes into 74 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 63 from 74 leaves us with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 21

Moving on to step 3:
21 can be fit into 117 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 35.0
If we take 105 away from 117, we end up with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 21

On to step 4:
The number 21 fits into 123 5 times, leaving a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 355.0
If we take 105 away from 123, we end up with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 21

Advancing to step 5:
If we divide 182 by 21, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 3558.0
Subtracting 168 from 182 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 21

On to step 6:
If we divide 140 by 21, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 35586.0
If we subtract 126 from 140, we get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 21

Moving on to step 7:
The number 21 fits into 146 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 355866.0
Subtract 126 from 146 to get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 21

Step 8:
When dividing 205 by 21, we get 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 3558669.0
The remainder is 16 after subtracting 189 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3558669.7
The remainder is 13 after subtracting 147 from 160.
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 10:
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: 3558669.76
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
21 goes into 40 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 3558669.761
Subtracting 21 from 40 leaves us 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.

Let's proceed to step 12:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 3558669.7619
The remainder is 1 after subtracting 189 from 190.
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:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3558669.7619
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.

Going ahead to step 14:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 3558669.761904
Deduct 84 from 100 and we're left 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.

Going ahead to step 15:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 3558669.7619047
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.

Step 16:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3558669.76190476
Subtracting 126 from 130 leaves us 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.

The final outcome is 3558669.76190476, with a leftover of 4e-09.
