737474 ÷ 21 
Let's see how many times 21 fits into 737474.

Step 1:
7 divided by 21 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 21

Let's proceed to step 2:
21 goes into 73 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 10 after subtracting 63 from 73.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 21

Step 3:
107 divided by 21 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 105 from 107, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 21

Going ahead to step 4:
If we divide 24 by 21, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 351.0
The remainder is 3 after subtracting 21 from 24.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 21

Let's proceed to step 5:
21 goes into 37 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 3511.0
If we subtract 21 from 37, we get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 21

Advancing to step 6:
21 can be fit into 164 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 35117.0
The remainder is 17 after subtracting 147 from 164.
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 7:
When dividing 170 by 21, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 35117.8
Subtracting 168 from 170 leaves us 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.

On to step 8:
20 divided by 21 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 35117.8
Subtracting 0 from 20 leaves us 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.

Advancing to step 9:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 35117.809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35117.8095
Deduct 105 from 110 and we're left 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.

Going ahead to step 11:
50 divided by 21 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 35117.80952
Subtracting 42 from 50 leaves us 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.

Let's proceed to step 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 35117.809523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
When dividing 170 by 21, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 35117.8095238
Deduct 168 from 170 and we're left 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.

Going ahead to step 14:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 35117.8095238
Subtracting 0 from 20 leaves us 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.

The final outcome is 35117.8095238, with a leftover of 2e-08.
