We divide 737658 by 21
We want to figure out the number of times 737658 can be divided by 21.

On to step 1:
21 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 21

Step 2:
73 divided by 21 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 63 from 73 and we're left with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Step 3:
107 divided by 21 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 105 from 107 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

Step 4:
21 can be fit into 26 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 351.0
If we take 21 away from 26, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 21

On to step 5:
If we divide 55 by 21, we get 2 and a remainder of 13.
The next digit of our result is 2. 
Result so far: 3512.0
Deduct 42 from 55 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 21

Advancing to step 6:
The number 21 fits into 138 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 35126.0
The remainder is 12 after subtracting 126 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 21, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 35126.5
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 35126.57
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 35126.571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 35126.5714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
60 divided by 21 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 35126.57142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 35126.571428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 35126.5714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 35126.57142857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 35126.57142857 with a remainder of 3e-09.
