We divide 378974 by 66
We're looking to find how many times 66 goes into 378974.

Step 1:
66 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 66

Moving on to step 2:
If we divide 37 by 66, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 66

Advancing to step 3:
If we divide 378 by 66, we get 5 and a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 330 from 378 to get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 66

On to step 4:
489 divided by 66 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 27 after subtracting 462 from 489.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 66

Advancing to step 5:
66 can be fit into 277 4 times, resulting in a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 574.0
Subtracting 264 from 277 leaves us with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 66

Going ahead to step 6:
When dividing 134 by 66, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 5742.0
If we subtract 132 from 134, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 66 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 5742.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 66, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 5742.03
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
20 divided by 66 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5742.03
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 5742.0303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
If we divide 20 by 66, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5742.0303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 5742.030303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5742.030303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
When dividing 200 by 66, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 5742.03030303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 5742.03030303 with a remaining 2e-09.
