54495664 ÷ 122 
We want to divide 54495664 by 122.

Step 1:
If we divide 5 by 122, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 122

On to step 2:
If we divide 54 by 122, we get 0 and a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 122

Moving on to step 3:
122 can be fit into 544 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 488 from 544 to get 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 122

Advancing to step 4:
122 can be fit into 569 4 times, resulting in a remainder of 81.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 81 after subtracting 488 from 569.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 122

Step 5:
815 divided by 122 is 6 with a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 446.0
Deduct 732 from 815 and we're left with 83.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 122

Step 6:
The number 122 fits into 836 6 times, leaving a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 4466.0
Deduct 732 from 836 and we're left with 104.
Grab the next digit (6) from the dividend, add it to 104, then carry on: 1046 / 122

Step 7:
If we divide 1046 by 122, we get 8 and a remainder of 70.
The next digit of our result is 8. 
Result so far: 44668.0
If we take 976 away from 1046, we end up with 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 122

Moving on to step 8:
The number 122 fits into 704 5 times, leaving a remainder of 94.
Write down 5 as next digit of the result. 
Result so far: 446685.0
Subtracting 610 from 704 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 9:
When dividing 940 by 122, we get 7 with a remainder of 86.
The number 7 becomes the next digit in our result. 
Result so far: 446685.7
Subtracting 854 from 940 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 10:
When dividing 860 by 122, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 446685.77
Subtract 854 from 860 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 446685.77, with a leftover of 0.006.
