We look at the division of 91668458 by 58 
We're looking to find how many times 58 goes into 91668458.

Moving on to step 1:
58 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
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 / 58

Let's proceed to step 2:
58 goes into 91 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 58 from 91 leaves us with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 58

Moving on to step 3:
58 can be fit into 336 5 times, resulting in a remainder of 46.
The next digit of our result is 5. 
Result so far: 15.0
If we take 290 away from 336, we end up with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 58

Step 4:
58 goes into 466 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 158.0
Deduct 464 from 466 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 58

Moving on to step 5:
28 divided by 58 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 1580.0
Subtract 0 from 28 to get 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 58

Going ahead to step 6:
When dividing 284 by 58, we get 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 15804.0
Subtract 232 from 284 to get 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 58

Going ahead to step 7:
When dividing 525 by 58, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 158049.0
If we subtract 522 from 525, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 58

Going ahead to step 8:
58 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 1580490.0
The remainder is 38 after subtracting 0 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
If we divide 380 by 58, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 1580490.6
Subtract 348 from 380 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.

Step 10:
58 can be fit into 320 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1580490.65
Subtracting 290 from 320 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
58 can be fit into 300 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1580490.655
Subtract 290 from 300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 1580490.655 with a remainder of 0.001.
