49836590 ÷ 558 
We want to figure out the number of times 49836590 can be divided by 558.

Advancing to step 1:
558 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 558

Advancing to step 2:
When dividing 49 by 558, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 558

Going ahead to step 3:
558 can be fit into 498 0 times, resulting in a remainder of 498.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 498 to get 498.
Grab the next digit (3) from the dividend, add it to 498, then carry on: 4983 / 558

Let's proceed to step 4:
The number 558 fits into 4983 8 times, leaving a remainder of 519.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 4464 from 4983, we get 519.
Bring next digit (6) of the dividend behind the 519 and repeat the process: 5196 / 558

Moving on to step 5:
5196 divided by 558 is 9 with a remainder of 174.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 5022 away from 5196, we end up with 174.
Grab the next digit (5) from the dividend, add it to 174, then carry on: 1745 / 558

Advancing to step 6:
The number 558 fits into 1745 3 times, leaving a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 893.0
If we subtract 1674 from 1745, we get 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 558

Step 7:
719 divided by 558 is 1 with a remainder of 161.
The next digit of our result is 1. 
Result so far: 8931.0
Deduct 558 from 719 and we're left with 161.
Append the next digit (0) from the dividend to 161 and continue with: 1610 / 558

Step 8:
1610 divided by 558 is 2 with a remainder of 494.
Record the quotient 2 as the next digit in the result. 
Result so far: 89312.0
Subtracting 1116 from 1610 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 9:
If we divide 4940 by 558, we get 8 and a remainder of 476.
Write down 8 as next digit of the result. 
Result so far: 89312.8
If we subtract 4464 from 4940, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 10:
The number 558 fits into 4760 8 times, leaving a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 89312.88
If we take 4464 away from 4760, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 89312.88 with a remainder of 0.296.
