21432509 ÷ 61 
We're looking to find how many times 61 goes into 21432509.

Moving on to step 1:
If we divide 2 by 61, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 61

Step 2:
21 divided by 61 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 61

Advancing to step 3:
The number 61 fits into 214 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 183 from 214 and we're left with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 61

Step 4:
The number 61 fits into 313 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 305 from 313, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 61

On to step 5:
If we divide 82 by 61, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 351.0
Subtract 61 from 82 to get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 61

Step 6:
When dividing 215 by 61, we get 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 3513.0
Subtracting 183 from 215 leaves us with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 61

Advancing to step 7:
61 can be fit into 320 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 35135.0
Subtracting 305 from 320 leaves us with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 61

Advancing to step 8:
If we divide 159 by 61, we get 2 and a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 351352.0
Subtract 122 from 159 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
370 divided by 61 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 351352.6
Subtract 366 from 370 to 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:
When dividing 40 by 61, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 351352.6
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
61 goes into 400 6 times with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 351352.606
If we take 366 away from 400, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
61 can be fit into 340 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 351352.6065
Deduct 305 from 340 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
61 goes into 350 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 351352.60655
Subtracting 305 from 350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 351352.60655 with a balance of 4.5e-05.
