22561522 ÷ 345 
We want to figure out the number of times 22561522 can be divided by 345.

On to step 1:
The number 345 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 345

Step 2:
22 divided by 345 is 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 345

Advancing to step 3:
The number 345 fits into 225 0 times, leaving a remainder of 225.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 225, we end up with 225.
Grab the next digit (6) from the dividend, add it to 225, then carry on: 2256 / 345

Moving on to step 4:
345 can be fit into 2256 6 times, resulting in a remainder of 186.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 186 after subtracting 2070 from 2256.
Grab the next digit (1) from the dividend, add it to 186, then carry on: 1861 / 345

Going ahead to step 5:
345 goes into 1861 5 times with a remainder of 136.
The next digit of our result is 5. 
Result so far: 65.0
If we subtract 1725 from 1861, we get 136.
Include the next digit (5) from the dividend after 136, then repeat: 1365 / 345

Step 6:
1365 divided by 345 is 3 with a remainder of 330.
Use 3 as the next digit of our solution. 
Result so far: 653.0
The remainder is 330 after subtracting 1035 from 1365.
Grab the next digit (2) from the dividend, add it to 330, then carry on: 3302 / 345

Step 7:
If we divide 3302 by 345, we get 9 and a remainder of 197.
The next digit of our result is 9. 
Result so far: 6539.0
If we subtract 3105 from 3302, we get 197.
Include the next digit (2) from the dividend after 197, then repeat: 1972 / 345

Going ahead to step 8:
If we divide 1972 by 345, we get 5 and a remainder of 247.
The next digit of our result is 5. 
Result so far: 65395.0
Subtracting 1725 from 1972 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 9:
If we divide 2470 by 345, we get 7 and a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 65395.7
If we subtract 2415 from 2470, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
345 can be fit into 550 1 times, resulting in a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 65395.71
If we subtract 345 from 550, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 11:
345 goes into 2050 5 times with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 65395.715
Subtract 1725 from 2050 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 12:
345 goes into 3250 9 times with a remainder of 145.
Record the quotient 9 as the next digit in the result. 
Result so far: 65395.7159
The remainder is 145 after subtracting 3105 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 13:
345 goes into 1450 4 times with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 65395.71594
If we subtract 1380 from 1450, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
When dividing 700 by 345, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 65395.715942
The remainder is 10 after subtracting 690 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
345 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 65395.715942
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
345 goes into 1000 2 times with a remainder of 310.
Use 2 as the next digit of our solution. 
Result so far: 65395.71594202
If we subtract 690 from 1000, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final result is 65395.71594202 with a remainder of 3.1e-07.
