66911020 ÷ 52 
Let's see how many times 52 fits into 66911020.

Step 1:
52 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 52

Advancing to step 2:
The number 52 fits into 66 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 52 from 66 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 52

Advancing to step 3:
If we divide 149 by 52, we get 2 and a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 104 from 149 leaves us with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 52

Let's proceed to step 4:
52 goes into 451 8 times with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Subtracting 416 from 451 leaves us with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 52

Advancing to step 5:
52 can be fit into 351 6 times, resulting in a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 1286.0
The remainder is 39 after subtracting 312 from 351.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 52

Going ahead to step 6:
When dividing 390 by 52, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 12867.0
If we subtract 364 from 390, we get 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 52

Advancing to step 7:
When dividing 262 by 52, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 128675.0
Subtracting 260 from 262 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 52

Advancing to step 8:
52 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1286750.0
If we take 0 away from 20, we end up 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.

Going ahead to step 9:
52 goes into 200 3 times with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 1286750.3
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
440 divided by 52 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1286750.38
Subtracting 416 from 440 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
The number 52 fits into 240 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 1286750.384
Deduct 208 from 240 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
320 divided by 52 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1286750.3846
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
The number 52 fits into 80 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1286750.38461
Subtract 52 from 80 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
52 goes into 280 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 1286750.384615
Deduct 260 from 280 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.

On to step 15:
The number 52 fits into 200 3 times, leaving a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 1286750.3846153
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 16:
If we divide 440 by 52, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1286750.38461538
The remainder is 24 after subtracting 416 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 1286750.38461538 with a remainder of 2.4e-08.
