21942509 ÷ 113 
We're looking to find how many times 113 goes into 21942509.

Moving on to step 1:
113 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 113

Moving on to step 2:
If we divide 21 by 113, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 113

Moving on to step 3:
The number 113 fits into 219 1 times, leaving a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 113 from 219, we get 106.
Grab the next digit (4) from the dividend, add it to 106, then carry on: 1064 / 113

Step 4:
When dividing 1064 by 113, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 1017 from 1064 to get 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 113

Moving on to step 5:
113 goes into 472 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 194.0
The remainder is 20 after subtracting 452 from 472.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 113

On to step 6:
The number 113 fits into 205 1 times, leaving a remainder of 92.
The next digit of our result is 1. 
Result so far: 1941.0
If we subtract 113 from 205, we get 92.
Include the next digit (0) from the dividend after 92, then repeat: 920 / 113

Advancing to step 7:
113 can be fit into 920 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 19418.0
The remainder is 16 after subtracting 904 from 920.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 113

Let's proceed to step 8:
The number 113 fits into 169 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 194181.0
Deduct 113 from 169 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
If we divide 560 by 113, we get 4 and a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 194181.4
The remainder is 108 after subtracting 452 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
113 can be fit into 1080 9 times, resulting in a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 194181.49
If we subtract 1017 from 1080, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 11:
630 divided by 113 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 194181.495
Subtract 565 from 630 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 12:
If we divide 650 by 113, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 194181.4955
If we take 565 away from 650, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 194181.4955, with a leftover of 0.00085.
