91659623 divided by 558 
Let's see how many times 558 fits into 91659623.

Going ahead to step 1:
If we divide 9 by 558, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 558

Moving on to step 2:
If we divide 91 by 558, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 558

Advancing to step 3:
When dividing 916 by 558, we get 1 with a remainder of 358.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 558 from 916, we get 358.
Fetch the next digit (5) from the dividend, attach it to 358 and continue: 3585 / 558

Moving on to step 4:
When dividing 3585 by 558, we get 6 with a remainder of 237.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 3348 from 3585 leaves us with 237.
Grab the next digit (9) from the dividend, add it to 237, then carry on: 2379 / 558

On to step 5:
If we divide 2379 by 558, we get 4 and a remainder of 147.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtracting 2232 from 2379 leaves us with 147.
Bring next digit (6) of the dividend behind the 147 and repeat the process: 1476 / 558

On to step 6:
1476 divided by 558 is 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 1642.0
The remainder is 360 after subtracting 1116 from 1476.
Take the next digit (2) from the dividend and append it to 360, then repeat: 3602 / 558

Step 7:
If we divide 3602 by 558, we get 6 and a remainder of 254.
Record the quotient 6 as the next digit in the result. 
Result so far: 16426.0
Subtracting 3348 from 3602 leaves us with 254.
Fetch the next digit (3) from the dividend, attach it to 254 and continue: 2543 / 558

Moving on to step 8:
The number 558 fits into 2543 4 times, leaving a remainder of 311.
Use 4 as the next digit of our solution. 
Result so far: 164264.0
If we take 2232 away from 2543, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 9:
3110 divided by 558 is 5 with a remainder of 320.
The next digit of our result is 5. 
Result so far: 164264.5
If we take 2790 away from 3110, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
If we divide 3200 by 558, we get 5 and a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 164264.55
Deduct 2790 from 3200 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

In conclusion, the division gives 164264.55 with a balance of 0.41.
