We divide 370765 by 21
We're looking to find how many times 21 goes into 370765.

Step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 21

Advancing to step 2:
The number 21 fits into 37 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 21 from 37 to get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 21

Moving on to step 3:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 147 from 160 leaves us with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 21

Going ahead to step 4:
137 divided by 21 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 176.0
The remainder is 11 after subtracting 126 from 137.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 21

On to step 5:
The number 21 fits into 116 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 1765.0
If we subtract 105 from 116, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 21

On to step 6:
The number 21 fits into 115 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 17655.0
If we subtract 105 from 115, we get 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 7:
When dividing 100 by 21, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 17655.4
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.

Step 8:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 17655.47
Deduct 147 from 160 and we're left with 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 9:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 17655.476
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.

Moving on to step 10:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 17655.4761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 17655.47619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17655.47619
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 13:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 17655.4761904
If we subtract 84 from 100, we 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.

Advancing to step 14:
21 goes into 160 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 17655.47619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 17655.47619047, with a leftover of 1.3e-08.
