We're dividing 22404357 by 166 
We want to figure out the number of times 22404357 can be divided by 166.

Going ahead to step 1:
If we divide 2 by 166, 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.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 166

On to step 2:
The number 166 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 166

Going ahead to step 3:
If we divide 224 by 166, we get 1 and a remainder of 58.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 166 from 224 to get 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 166

Advancing to step 4:
580 divided by 166 is 3 with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 498 from 580 leaves us with 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 166

Step 5:
When dividing 824 by 166, we get 4 with a remainder of 160.
The next digit of our result is 4. 
Result so far: 134.0
Subtracting 664 from 824 leaves us with 160.
Bring next digit (3) of the dividend behind the 160 and repeat the process: 1603 / 166

Let's proceed to step 6:
If we divide 1603 by 166, we get 9 and a remainder of 109.
Put 9 as the next digit of the answer. 
Result so far: 1349.0
Subtract 1494 from 1603 to get 109.
Include the next digit (5) from the dividend after 109, then repeat: 1095 / 166

Let's proceed to step 7:
166 goes into 1095 6 times with a remainder of 99.
The next digit of our result is 6. 
Result so far: 13496.0
If we subtract 996 from 1095, we get 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 166

Let's proceed to step 8:
997 divided by 166 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 134966.0
The remainder is 1 after subtracting 996 from 997.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 166, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 134966.0
If we take 0 away from 10, we end up with 10.
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 10:
When dividing 100 by 166, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 134966.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 134966.0 with a remaining 0.1.
