68520389 ÷ 558 
We're looking to find how many times 558 goes into 68520389.

Advancing to step 1:
The number 558 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 558

Let's proceed to step 2:
68 divided by 558 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 558

Let's proceed to step 3:
685 divided by 558 is 1 with a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 558 from 685, we get 127.
Append the next digit (2) from the dividend to 127 and continue with: 1272 / 558

Going ahead to step 4:
If we divide 1272 by 558, we get 2 and a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1116 away from 1272, we end up with 156.
Take the next digit (0) from the dividend and append it to 156, then repeat: 1560 / 558

On to step 5:
If we divide 1560 by 558, we get 2 and a remainder of 444.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtracting 1116 from 1560 leaves us with 444.
Grab the next digit (3) from the dividend, add it to 444, then carry on: 4443 / 558

On to step 6:
When dividing 4443 by 558, we get 7 with a remainder of 537.
Use 7 as the next digit of our solution. 
Result so far: 1227.0
Subtract 3906 from 4443 to get 537.
Take the next digit (8) from the dividend and append it to 537, then repeat: 5378 / 558

Going ahead to step 7:
The number 558 fits into 5378 9 times, leaving a remainder of 356.
Record the quotient 9 as the next digit in the result. 
Result so far: 12279.0
If we subtract 5022 from 5378, we get 356.
Include the next digit (9) from the dividend after 356, then repeat: 3569 / 558

Moving on to step 8:
When dividing 3569 by 558, we get 6 with a remainder of 221.
Put 6 as the next digit of the answer. 
Result so far: 122796.0
Subtract 3348 from 3569 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Let's proceed to step 9:
2210 divided by 558 is 3 with a remainder of 536.
Use 3 as the next digit of our solution. 
Result so far: 122796.3
The remainder is 536 after subtracting 1674 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 10:
558 goes into 5360 9 times with a remainder of 338.
Use 9 as the next digit of our solution. 
Result so far: 122796.39
Subtract 5022 from 5360 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 11:
558 goes into 3380 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 122796.396
Subtract 3348 from 3380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
558 can be fit into 320 0 times, resulting in a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 122796.396
Deduct 0 from 320 and we're left 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.

Advancing to step 13:
558 can be fit into 3200 5 times, resulting in a remainder of 410.
The number 5 becomes the next digit in our result. 
Result so far: 122796.39605
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.

Step 14:
558 can be fit into 4100 7 times, resulting in a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 122796.396057
Subtracting 3906 from 4100 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 15:
If we divide 1940 by 558, we get 3 and a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 122796.3960573
If we subtract 1674 from 1940, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 16:
The number 558 fits into 2660 4 times, leaving a remainder of 428.
Put 4 as the next digit of the answer. 
Result so far: 122796.39605734
The remainder is 428 after subtracting 2232 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

After the division, we end up with 122796.39605734 and a remainder of 4.28e-07.
