55778511 ÷ 538 
We want to figure out the number of times 55778511 can be divided by 538.

Advancing to step 1:
538 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 538

Let's proceed to step 2:
55 divided by 538 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 538

Let's proceed to step 3:
557 divided by 538 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 538 from 557 and we're left with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 538

Moving on to step 4:
When dividing 197 by 538, we get 0 with a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 197 leaves us with 197.
Bring next digit (8) of the dividend behind the 197 and repeat the process: 1978 / 538

Moving on to step 5:
The number 538 fits into 1978 3 times, leaving a remainder of 364.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
The remainder is 364 after subtracting 1614 from 1978.
Take the next digit (5) from the dividend and append it to 364, then repeat: 3645 / 538

Moving on to step 6:
If we divide 3645 by 538, we get 6 and a remainder of 417.
Put 6 as the next digit of the answer. 
Result so far: 1036.0
If we subtract 3228 from 3645, we get 417.
Fetch the next digit (1) from the dividend, attach it to 417 and continue: 4171 / 538

Let's proceed to step 7:
If we divide 4171 by 538, we get 7 and a remainder of 405.
The next digit of our result is 7. 
Result so far: 10367.0
If we take 3766 away from 4171, we end up with 405.
Fetch the next digit (1) from the dividend, attach it to 405 and continue: 4051 / 538

Moving on to step 8:
4051 divided by 538 is 7 with a remainder of 285.
The next digit of our result is 7. 
Result so far: 103677.0
Subtract 3766 from 4051 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 9:
When dividing 2850 by 538, we get 5 with a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 103677.5
Deduct 2690 from 2850 and we're left 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.

Going ahead to step 10:
When dividing 1600 by 538, we get 2 with a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 103677.52
If we take 1076 away from 1600, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 11:
The number 538 fits into 5240 9 times, leaving a remainder of 398.
The number 9 becomes the next digit in our result. 
Result so far: 103677.529
If we subtract 4842 from 5240, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 12:
3980 divided by 538 is 7 with a remainder of 214.
Put 7 as the next digit of the answer. 
Result so far: 103677.5297
Deduct 3766 from 3980 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 13:
538 can be fit into 2140 3 times, resulting in a remainder of 526.
Record the quotient 3 as the next digit in the result. 
Result so far: 103677.52973
Deduct 1614 from 2140 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 14:
538 goes into 5260 9 times with a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 103677.529739
If we subtract 4842 from 5260, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 15:
If we divide 4180 by 538, we get 7 and a remainder of 414.
Record the quotient 7 as the next digit in the result. 
Result so far: 103677.5297397
If we subtract 3766 from 4180, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 16:
538 can be fit into 4140 7 times, resulting in a remainder of 374.
Put 7 as the next digit of the answer. 
Result so far: 103677.52973977
Deduct 3766 from 4140 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

After the division, we end up with 103677.52973977 and a remainder of 3.74e-07.
