58879346 divided by 86 
Our goal is to divide 58879346 by 86.

Step 1:
When dividing 5 by 86, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 86

Moving on to step 2:
When dividing 58 by 86, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 86

On to step 3:
If we divide 588 by 86, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 516 away from 588, we end up with 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 86

Advancing to step 4:
86 can be fit into 727 8 times, resulting in a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtract 688 from 727 to get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 86

Moving on to step 5:
86 can be fit into 399 4 times, resulting in a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 684.0
If we subtract 344 from 399, we get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 86

Going ahead to step 6:
If we divide 553 by 86, we get 6 and a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 6846.0
The remainder is 37 after subtracting 516 from 553.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 86

Advancing to step 7:
If we divide 374 by 86, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 68464.0
Subtracting 344 from 374 leaves us with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 86

Let's proceed to step 8:
86 can be fit into 306 3 times, resulting in a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 684643.0
Deduct 258 from 306 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
480 divided by 86 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 684643.5
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 86, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 684643.55
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 684643.55 with a remainder of 0.07.
