Let's divide 91389434 by 555
We're looking to find how many times 555 goes into 91389434.

Step 1:
If we divide 9 by 555, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 555

Step 2:
When dividing 91 by 555, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 555

On to step 3:
555 goes into 913 1 times with a remainder of 358.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 555 from 913 leaves us with 358.
Include the next digit (8) from the dividend after 358, then repeat: 3588 / 555

Going ahead to step 4:
The number 555 fits into 3588 6 times, leaving a remainder of 258.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 3330 from 3588 and we're left with 258.
Take the next digit (9) from the dividend and append it to 258, then repeat: 2589 / 555

On to step 5:
If we divide 2589 by 555, we get 4 and a remainder of 369.
Put 4 as the next digit of the answer. 
Result so far: 164.0
The remainder is 369 after subtracting 2220 from 2589.
Append the next digit (4) from the dividend to 369 and continue with: 3694 / 555

Moving on to step 6:
555 goes into 3694 6 times with a remainder of 364.
The number 6 becomes the next digit in our result. 
Result so far: 1646.0
If we subtract 3330 from 3694, we get 364.
Include the next digit (3) from the dividend after 364, then repeat: 3643 / 555

Going ahead to step 7:
555 goes into 3643 6 times with a remainder of 313.
Record the quotient 6 as the next digit in the result. 
Result so far: 16466.0
If we subtract 3330 from 3643, we get 313.
Take the next digit (4) from the dividend and append it to 313, then repeat: 3134 / 555

Advancing to step 8:
When dividing 3134 by 555, we get 5 with a remainder of 359.
Put 5 as the next digit of the answer. 
Result so far: 164665.0
Deduct 2775 from 3134 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 9:
The number 555 fits into 3590 6 times, leaving a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 164665.6
The remainder is 260 after subtracting 3330 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
2600 divided by 555 is 4 with a remainder of 380.
The next digit of our result is 4. 
Result so far: 164665.64
If we take 2220 away from 2600, we end up 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.

Step 11:
When dividing 3800 by 555, we get 6 with a remainder of 470.
Record the quotient 6 as the next digit in the result. 
Result so far: 164665.646
Deduct 3330 from 3800 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 12:
When dividing 4700 by 555, we get 8 with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 164665.6468
The remainder is 260 after subtracting 4440 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
If we divide 2600 by 555, we get 4 and a remainder of 380.
Use 4 as the next digit of our solution. 
Result so far: 164665.64684
Subtract 2220 from 2600 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
The number 555 fits into 3800 6 times, leaving a remainder of 470.
Record the quotient 6 as the next digit in the result. 
Result so far: 164665.646846
If we subtract 3330 from 3800, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 15:
4700 divided by 555 is 8 with a remainder of 260.
Record the quotient 8 as the next digit in the result. 
Result so far: 164665.6468468
If we subtract 4440 from 4700, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
2600 divided by 555 is 4 with a remainder of 380.
Write down 4 as next digit of the result. 
Result so far: 164665.64684684
Subtract 2220 from 2600 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 164665.64684684 with a remainder of 3.8e-07.
