We look at the division of 55643415 by 909 
We want to figure out the number of times 55643415 can be divided by 909.

Advancing to step 1:
909 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 909

Let's proceed to step 2:
When dividing 55 by 909, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 909

On to step 3:
If we divide 556 by 909, we get 0 and a remainder of 556.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 556, we end up with 556.
Append the next digit (4) from the dividend to 556 and continue with: 5564 / 909

Moving on to step 4:
The number 909 fits into 5564 6 times, leaving a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 5454 from 5564 leaves us with 110.
Take the next digit (3) from the dividend and append it to 110, then repeat: 1103 / 909

Step 5:
1103 divided by 909 is 1 with a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 909 away from 1103, we end up with 194.
Grab the next digit (4) from the dividend, add it to 194, then carry on: 1944 / 909

Going ahead to step 6:
When dividing 1944 by 909, we get 2 with a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 612.0
If we take 1818 away from 1944, we end up with 126.
Append the next digit (1) from the dividend to 126 and continue with: 1261 / 909

Let's proceed to step 7:
If we divide 1261 by 909, we get 1 and a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 6121.0
Subtracting 909 from 1261 leaves us with 352.
Fetch the next digit (5) from the dividend, attach it to 352 and continue: 3525 / 909

Going ahead to step 8:
When dividing 3525 by 909, we get 3 with a remainder of 798.
The next digit of our result is 3. 
Result so far: 61213.0
If we take 2727 away from 3525, we end up with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Going ahead to step 9:
909 goes into 7980 8 times with a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 61213.8
Subtract 7272 from 7980 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Going ahead to step 10:
The number 909 fits into 7080 7 times, leaving a remainder of 717.
The next digit of our result is 7. 
Result so far: 61213.87
If we take 6363 away from 7080, we end up with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Let's proceed to step 11:
The number 909 fits into 7170 7 times, leaving a remainder of 807.
The number 7 becomes the next digit in our result. 
Result so far: 61213.877
If we subtract 6363 from 7170, we get 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

The quotient of the division is 61213.877, and the remainder is 0.0807.
