We're dividing 53664643 by 912 
Our goal is to divide 53664643 by 912.

Going ahead to step 1:
912 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 912

Advancing to step 2:
912 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 912

Step 3:
The number 912 fits into 536 0 times, leaving a remainder of 536.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 536, we end up with 536.
Append the next digit (6) from the dividend to 536 and continue with: 5366 / 912

Step 4:
912 goes into 5366 5 times with a remainder of 806.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4560 from 5366 and we're left with 806.
Take the next digit (4) from the dividend and append it to 806, then repeat: 8064 / 912

Going ahead to step 5:
The number 912 fits into 8064 8 times, leaving a remainder of 768.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
The remainder is 768 after subtracting 7296 from 8064.
Grab the next digit (6) from the dividend, add it to 768, then carry on: 7686 / 912

Let's proceed to step 6:
The number 912 fits into 7686 8 times, leaving a remainder of 390.
Put 8 as the next digit of the answer. 
Result so far: 588.0
If we subtract 7296 from 7686, we get 390.
Take the next digit (4) from the dividend and append it to 390, then repeat: 3904 / 912

Going ahead to step 7:
912 goes into 3904 4 times with a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 5884.0
If we subtract 3648 from 3904, we get 256.
Take the next digit (3) from the dividend and append it to 256, then repeat: 2563 / 912

Going ahead to step 8:
2563 divided by 912 is 2 with a remainder of 739.
The next digit of our result is 2. 
Result so far: 58842.0
Subtract 1824 from 2563 to get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Let's proceed to step 9:
The number 912 fits into 7390 8 times, leaving a remainder of 94.
Write down 8 as next digit of the result. 
Result so far: 58842.8
The remainder is 94 after subtracting 7296 from 7390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
912 goes into 940 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 58842.81
Deduct 912 from 940 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
912 can be fit into 280 0 times, resulting in a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 58842.81
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
912 can be fit into 2800 3 times, resulting in a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 58842.8103
The remainder is 64 after subtracting 2736 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
If we divide 640 by 912, we get 0 and a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 58842.8103
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 14:
6400 divided by 912 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 58842.810307
Subtract 6384 from 6400 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
160 divided by 912 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 58842.810307
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
912 can be fit into 1600 1 times, resulting in a remainder of 688.
The number 1 becomes the next digit in our result. 
Result so far: 58842.81030701
If we take 912 away from 1600, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

The final result is 58842.81030701 with a remainder of 6.88e-07.
