91717764 ÷ 554 
We want to figure out the number of times 91717764 can be divided by 554.

On to step 1:
If we divide 9 by 554, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 554

Moving on to step 2:
91 divided by 554 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 554

Step 3:
917 divided by 554 is 1 with a remainder of 363.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 363 after subtracting 554 from 917.
Append the next digit (1) from the dividend to 363 and continue with: 3631 / 554

Advancing to step 4:
554 can be fit into 3631 6 times, resulting in a remainder of 307.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 3324 from 3631 leaves us with 307.
Append the next digit (7) from the dividend to 307 and continue with: 3077 / 554

Step 5:
554 goes into 3077 5 times with a remainder of 307.
Put 5 as the next digit of the answer. 
Result so far: 165.0
Subtract 2770 from 3077 to get 307.
Bring next digit (7) of the dividend behind the 307 and repeat the process: 3077 / 554

Going ahead to step 6:
554 can be fit into 3077 5 times, resulting in a remainder of 307.
Record the quotient 5 as the next digit in the result. 
Result so far: 1655.0
Subtracting 2770 from 3077 leaves us with 307.
Fetch the next digit (6) from the dividend, attach it to 307 and continue: 3076 / 554

Moving on to step 7:
When dividing 3076 by 554, we get 5 with a remainder of 306.
The next digit of our result is 5. 
Result so far: 16555.0
Subtract 2770 from 3076 to get 306.
Fetch the next digit (4) from the dividend, attach it to 306 and continue: 3064 / 554

Step 8:
When dividing 3064 by 554, we get 5 with a remainder of 294.
The number 5 becomes the next digit in our result. 
Result so far: 165555.0
Deduct 2770 from 3064 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 9:
The number 554 fits into 2940 5 times, leaving a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 165555.5
If we take 2770 away from 2940, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
The number 554 fits into 1700 3 times, leaving a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 165555.53
Subtracting 1662 from 1700 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
380 divided by 554 is 0 with a remainder of 380.
The next digit of our result is 0. 
Result so far: 165555.53
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
If we divide 3800 by 554, we get 6 and a remainder of 476.
Write down 6 as next digit of the result. 
Result so far: 165555.5306
If we take 3324 away from 3800, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 13:
4760 divided by 554 is 8 with a remainder of 328.
The next digit of our result is 8. 
Result so far: 165555.53068
If we subtract 4432 from 4760, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 14:
The number 554 fits into 3280 5 times, leaving a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 165555.530685
If we take 2770 away from 3280, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 15:
The number 554 fits into 5100 9 times, leaving a remainder of 114.
Use 9 as the next digit of our solution. 
Result so far: 165555.5306859
Deduct 4986 from 5100 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 16:
When dividing 1140 by 554, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 165555.53068592
Deduct 1108 from 1140 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 165555.53068592, with a leftover of 3.2e-08.
