We're dividing 66108433 by 354 
We want to figure out the number of times 66108433 can be divided by 354.

On to step 1:
The number 354 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 354

Moving on to step 2:
When dividing 66 by 354, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 354

On to step 3:
354 goes into 661 1 times with a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 354 from 661 leaves us with 307.
Take the next digit (0) from the dividend and append it to 307, then repeat: 3070 / 354

Advancing to step 4:
When dividing 3070 by 354, we get 8 with a remainder of 238.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 2832 from 3070 and we're left with 238.
Take the next digit (8) from the dividend and append it to 238, then repeat: 2388 / 354

Advancing to step 5:
354 can be fit into 2388 6 times, resulting in a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 186.0
If we take 2124 away from 2388, we end up with 264.
Include the next digit (4) from the dividend after 264, then repeat: 2644 / 354

Let's proceed to step 6:
The number 354 fits into 2644 7 times, leaving a remainder of 166.
The number 7 becomes the next digit in our result. 
Result so far: 1867.0
Subtracting 2478 from 2644 leaves us with 166.
Take the next digit (3) from the dividend and append it to 166, then repeat: 1663 / 354

On to step 7:
The number 354 fits into 1663 4 times, leaving a remainder of 247.
Record the quotient 4 as the next digit in the result. 
Result so far: 18674.0
If we subtract 1416 from 1663, we get 247.
Append the next digit (3) from the dividend to 247 and continue with: 2473 / 354

On to step 8:
354 can be fit into 2473 6 times, resulting in a remainder of 349.
Write down 6 as next digit of the result. 
Result so far: 186746.0
Subtracting 2124 from 2473 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 9:
354 goes into 3490 9 times with a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 186746.9
If we subtract 3186 from 3490, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 10:
The number 354 fits into 3040 8 times, leaving a remainder of 208.
The next digit of our result is 8. 
Result so far: 186746.98
Subtract 2832 from 3040 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 11:
2080 divided by 354 is 5 with a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 186746.985
If we subtract 1770 from 2080, 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.

Moving on to step 12:
354 goes into 3100 8 times with a remainder of 268.
Record the quotient 8 as the next digit in the result. 
Result so far: 186746.9858
Subtracting 2832 from 3100 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 13:
354 goes into 2680 7 times with a remainder of 202.
The next digit of our result is 7. 
Result so far: 186746.98587
Subtract 2478 from 2680 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 14:
354 can be fit into 2020 5 times, resulting in a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 186746.985875
Subtracting 1770 from 2020 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 15:
The number 354 fits into 2500 7 times, leaving a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 186746.9858757
Deduct 2478 from 2500 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 16:
The number 354 fits into 220 0 times, leaving a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 186746.9858757
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 186746.9858757 and a remainder of 2.2e-07.
