We're dividing 55603866 by 964 
We want to figure out the number of times 55603866 can be divided by 964.

Advancing to step 1:
If we divide 5 by 964, 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.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 964

Moving on to step 2:
55 divided by 964 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 964

Moving on to step 3:
556 divided by 964 is 0 with a remainder of 556.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 556 and we're left with 556.
Fetch the next digit (0) from the dividend, attach it to 556 and continue: 5560 / 964

Going ahead to step 4:
When dividing 5560 by 964, we get 5 with a remainder of 740.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 4820 from 5560, we get 740.
Include the next digit (3) from the dividend after 740, then repeat: 7403 / 964

Going ahead to step 5:
964 goes into 7403 7 times with a remainder of 655.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 6748 from 7403 leaves us with 655.
Fetch the next digit (8) from the dividend, attach it to 655 and continue: 6558 / 964

Step 6:
964 can be fit into 6558 6 times, resulting in a remainder of 774.
The next digit of our result is 6. 
Result so far: 576.0
Subtracting 5784 from 6558 leaves us with 774.
Append the next digit (6) from the dividend to 774 and continue with: 7746 / 964

Let's proceed to step 7:
When dividing 7746 by 964, we get 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 5768.0
Subtracting 7712 from 7746 leaves us with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 964

On to step 8:
The number 964 fits into 346 0 times, leaving a remainder of 346.
The next digit of our result is 0. 
Result so far: 57680.0
Subtract 0 from 346 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 9:
964 goes into 3460 3 times with a remainder of 568.
Record the quotient 3 as the next digit in the result. 
Result so far: 57680.3
If we subtract 2892 from 3460, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 10:
964 goes into 5680 5 times with a remainder of 860.
Record the quotient 5 as the next digit in the result. 
Result so far: 57680.35
Deduct 4820 from 5680 and we're left with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Let's proceed to step 11:
964 goes into 8600 8 times with a remainder of 888.
Record the quotient 8 as the next digit in the result. 
Result so far: 57680.358
The remainder is 888 after subtracting 7712 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Moving on to step 12:
964 goes into 8880 9 times with a remainder of 204.
The next digit of our result is 9. 
Result so far: 57680.3589
If we subtract 8676 from 8880, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 13:
964 goes into 2040 2 times with a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 57680.35892
Subtracting 1928 from 2040 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 14:
964 goes into 1120 1 times with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 57680.358921
If we take 964 away from 1120, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 15:
If we divide 1560 by 964, we get 1 and a remainder of 596.
The number 1 becomes the next digit in our result. 
Result so far: 57680.3589211
Subtracting 964 from 1560 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

After the division, we end up with 57680.3589211 and a remainder of 5.96e-06.
