Let's divide 53443652 by 660
We're looking to find how many times 660 goes into 53443652.

On to step 1:
If we divide 5 by 660, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 660

Advancing to step 2:
660 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 660

Advancing to step 3:
If we divide 534 by 660, we get 0 and a remainder of 534.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 534 and we're left with 534.
Fetch the next digit (4) from the dividend, attach it to 534 and continue: 5344 / 660

Step 4:
The number 660 fits into 5344 8 times, leaving a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 5280 away from 5344, we end up with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 660

Advancing to step 5:
When dividing 643 by 660, we get 0 with a remainder of 643.
Write down 0 as next digit of the result. 
Result so far: 80.0
The remainder is 643 after subtracting 0 from 643.
Grab the next digit (6) from the dividend, add it to 643, then carry on: 6436 / 660

Advancing to step 6:
When dividing 6436 by 660, we get 9 with a remainder of 496.
The number 9 becomes the next digit in our result. 
Result so far: 809.0
Subtracting 5940 from 6436 leaves us with 496.
Take the next digit (5) from the dividend and append it to 496, then repeat: 4965 / 660

Moving on to step 7:
If we divide 4965 by 660, we get 7 and a remainder of 345.
Write down 7 as next digit of the result. 
Result so far: 8097.0
Deduct 4620 from 4965 and we're left with 345.
Take the next digit (2) from the dividend and append it to 345, then repeat: 3452 / 660

On to step 8:
3452 divided by 660 is 5 with a remainder of 152.
The next digit of our result is 5. 
Result so far: 80975.0
If we subtract 3300 from 3452, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 9:
660 goes into 1520 2 times with a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 80975.2
If we subtract 1320 from 1520, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
2000 divided by 660 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 80975.23
If we subtract 1980 from 2000, 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.

Moving on to step 11:
The number 660 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 80975.23
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
2000 divided by 660 is 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 80975.2303
If we take 1980 away from 2000, 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.

Moving on to step 13:
The number 660 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 80975.2303
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 14:
If we divide 2000 by 660, we get 3 and a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 80975.230303
Deduct 1980 from 2000 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 15:
The number 660 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 80975.230303
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
If we divide 2000 by 660, we get 3 and a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 80975.23030303
If we take 1980 away from 2000, 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.

After the division, we end up with 80975.23030303 and a remainder of 2e-08.
