37133 divided by 21 
We're looking to find how many times 21 goes into 37133.

Moving on to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 21

Advancing to step 2:
21 goes into 37 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 21 from 37 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 21

Step 3:
If we divide 161 by 21, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 147 away from 161, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 21

Advancing to step 4:
21 can be fit into 143 6 times, resulting in a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 176.0
If we take 126 away from 143, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 21

Advancing to step 5:
The number 21 fits into 173 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 1768.0
If we take 168 away from 173, we end up 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.

Step 6:
When dividing 50 by 21, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1768.2
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 21, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 1768.23
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
If we divide 170 by 21, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1768.238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1768.238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1768.23809
Subtract 189 from 200 to 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.

Advancing to step 11:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1768.238095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1768.2380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
When dividing 80 by 21, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 1768.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 1768.23809523 with a remainder of 1.7e-08.
