Let's divide 80341670 by 558
We're looking to find how many times 558 goes into 80341670.

Let's proceed to step 1:
The number 558 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 558

On to step 2:
558 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 558

Step 3:
The number 558 fits into 803 1 times, leaving a remainder of 245.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 558 away from 803, we end up with 245.
Fetch the next digit (4) from the dividend, attach it to 245 and continue: 2454 / 558

Advancing to step 4:
2454 divided by 558 is 4 with a remainder of 222.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2232 from 2454 leaves us with 222.
Bring next digit (1) of the dividend behind the 222 and repeat the process: 2221 / 558

On to step 5:
If we divide 2221 by 558, we get 3 and a remainder of 547.
Use 3 as the next digit of our solution. 
Result so far: 143.0
Deduct 1674 from 2221 and we're left with 547.
Append the next digit (6) from the dividend to 547 and continue with: 5476 / 558

On to step 6:
If we divide 5476 by 558, we get 9 and a remainder of 454.
Use 9 as the next digit of our solution. 
Result so far: 1439.0
The remainder is 454 after subtracting 5022 from 5476.
Include the next digit (7) from the dividend after 454, then repeat: 4547 / 558

Advancing to step 7:
The number 558 fits into 4547 8 times, leaving a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 14398.0
Subtract 4464 from 4547 to get 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 558

On to step 8:
558 goes into 830 1 times with a remainder of 272.
The next digit of our result is 1. 
Result so far: 143981.0
Deduct 558 from 830 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 9:
558 goes into 2720 4 times with a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 143981.4
The remainder is 488 after subtracting 2232 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 10:
The number 558 fits into 4880 8 times, leaving a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 143981.48
If we take 4464 away from 4880, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 11:
558 goes into 4160 7 times with a remainder of 254.
Use 7 as the next digit of our solution. 
Result so far: 143981.487
Subtract 3906 from 4160 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 12:
558 goes into 2540 4 times with a remainder of 308.
Use 4 as the next digit of our solution. 
Result so far: 143981.4874
Subtracting 2232 from 2540 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 13:
558 goes into 3080 5 times with a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 143981.48745
Deduct 2790 from 3080 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
When dividing 2900 by 558, we get 5 with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 143981.487455
If we take 2790 away from 2900, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 143981.487455 with a remainder of 1.1e-05.
