53307594 divided by 661 
Let's see how many times 661 fits into 53307594.

Moving on to step 1:
If we divide 5 by 661, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 661

On to step 2:
661 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 661

On to step 3:
661 can be fit into 533 0 times, resulting in a remainder of 533.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 533, we get 533.
Bring next digit (0) of the dividend behind the 533 and repeat the process: 5330 / 661

On to step 4:
If we divide 5330 by 661, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 5288 from 5330, we get 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 661

Step 5:
661 can be fit into 427 0 times, resulting in a remainder of 427.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 427, we end up with 427.
Bring next digit (5) of the dividend behind the 427 and repeat the process: 4275 / 661

On to step 6:
661 can be fit into 4275 6 times, resulting in a remainder of 309.
Put 6 as the next digit of the answer. 
Result so far: 806.0
Subtract 3966 from 4275 to get 309.
Bring next digit (9) of the dividend behind the 309 and repeat the process: 3099 / 661

Let's proceed to step 7:
When dividing 3099 by 661, we get 4 with a remainder of 455.
Record the quotient 4 as the next digit in the result. 
Result so far: 8064.0
Subtract 2644 from 3099 to get 455.
Fetch the next digit (4) from the dividend, attach it to 455 and continue: 4554 / 661

On to step 8:
If we divide 4554 by 661, we get 6 and a remainder of 588.
The number 6 becomes the next digit in our result. 
Result so far: 80646.0
If we subtract 3966 from 4554, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 9:
If we divide 5880 by 661, we get 8 and a remainder of 592.
Write down 8 as next digit of the result. 
Result so far: 80646.8
Subtract 5288 from 5880 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 10:
661 can be fit into 5920 8 times, resulting in a remainder of 632.
Use 8 as the next digit of our solution. 
Result so far: 80646.88
Subtracting 5288 from 5920 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

After the division, we end up with 80646.88 and a remainder of 0.632.
