111800 ÷ 66 
We want to figure out the number of times 111800 can be divided by 66.

On to step 1:
If we divide 1 by 66, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 66

Step 2:
66 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 66

Let's proceed to step 3:
If we divide 111 by 66, we get 1 and a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 45 after subtracting 66 from 111.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 66

Advancing to step 4:
66 goes into 458 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 396 from 458 and we're left with 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 66

Step 5:
If we divide 620 by 66, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtracting 594 from 620 leaves us with 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 66

On to step 6:
When dividing 260 by 66, we get 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 1693.0
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1693.9
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 1693.93
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
66 goes into 620 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1693.939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 1693.9393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
When dividing 620 by 66, we get 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 1693.93939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 1693.939393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
When dividing 620 by 66, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 1693.9393939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
66 goes into 260 3 times with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 1693.93939393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 1693.93939393 with a remaining 6.2e-08.
