21202403 ÷ 133 
We're looking to find how many times 133 goes into 21202403.

Advancing to step 1:
If we divide 2 by 133, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 133

Step 2:
133 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 133

Moving on to step 3:
The number 133 fits into 212 1 times, leaving a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 133 away from 212, we end up with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 133

Step 4:
133 goes into 790 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 665 from 790 to get 125.
Append the next digit (2) from the dividend to 125 and continue with: 1252 / 133

Advancing to step 5:
1252 divided by 133 is 9 with a remainder of 55.
The next digit of our result is 9. 
Result so far: 159.0
Deduct 1197 from 1252 and we're left with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 133

Going ahead to step 6:
133 goes into 554 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 1594.0
The remainder is 22 after subtracting 532 from 554.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 133

Let's proceed to step 7:
When dividing 220 by 133, we get 1 with a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 15941.0
Subtracting 133 from 220 leaves us with 87.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 133

Let's proceed to step 8:
133 goes into 873 6 times with a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 159416.0
Subtracting 798 from 873 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
750 divided by 133 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 159416.5
Subtract 665 from 750 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
850 divided by 133 is 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 159416.56
If we take 798 away from 850, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
The number 133 fits into 520 3 times, leaving a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 159416.563
If we take 399 away from 520, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 12:
133 goes into 1210 9 times with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 159416.5639
If we subtract 1197 from 1210, we 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.

On to step 13:
If we divide 130 by 133, we get 0 and a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 159416.5639
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
If we divide 1300 by 133, we get 9 and a remainder of 103.
Write down 9 as next digit of the result. 
Result so far: 159416.563909
The remainder is 103 after subtracting 1197 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 15:
The number 133 fits into 1030 7 times, leaving a remainder of 99.
Put 7 as the next digit of the answer. 
Result so far: 159416.5639097
Subtracting 931 from 1030 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 16:
The number 133 fits into 990 7 times, leaving a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 159416.56390977
If we take 931 away from 990, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 159416.56390977, with a leftover of 5.9e-08.
