58860687 ÷ 878 
Our goal is to divide 58860687 by 878.

Going ahead to step 1:
If we divide 5 by 878, we get 0 and a remainder of 5.
The next digit of our result is 0. 
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 / 878

Let's proceed to step 2:
The number 878 fits into 58 0 times, leaving a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Append the next digit (8) from the dividend to 58 and continue with: 588 / 878

Step 3:
588 divided by 878 is 0 with a remainder of 588.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 588, we get 588.
Take the next digit (6) from the dividend and append it to 588, then repeat: 5886 / 878

Going ahead to step 4:
5886 divided by 878 is 6 with a remainder of 618.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5268 from 5886 and we're left with 618.
Fetch the next digit (0) from the dividend, attach it to 618 and continue: 6180 / 878

On to step 5:
6180 divided by 878 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 6146 from 6180 and we're left with 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 878

Going ahead to step 6:
If we divide 346 by 878, we get 0 and a remainder of 346.
Record the quotient 0 as the next digit in the result. 
Result so far: 670.0
Subtract 0 from 346 to get 346.
Fetch the next digit (8) from the dividend, attach it to 346 and continue: 3468 / 878

Advancing to step 7:
878 goes into 3468 3 times with a remainder of 834.
Put 3 as the next digit of the answer. 
Result so far: 6703.0
Subtract 2634 from 3468 to get 834.
Grab the next digit (7) from the dividend, add it to 834, then carry on: 8347 / 878

Moving on to step 8:
The number 878 fits into 8347 9 times, leaving a remainder of 445.
Record the quotient 9 as the next digit in the result. 
Result so far: 67039.0
The remainder is 445 after subtracting 7902 from 8347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 9:
When dividing 4450 by 878, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 67039.5
Deduct 4390 from 4450 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
600 divided by 878 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 67039.5
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
The number 878 fits into 6000 6 times, leaving a remainder of 732.
Use 6 as the next digit of our solution. 
Result so far: 67039.506
If we take 5268 away from 6000, we end up with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Going ahead to step 12:
The number 878 fits into 7320 8 times, leaving a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 67039.5068
If we take 7024 away from 7320, 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.

Step 13:
The number 878 fits into 2960 3 times, leaving a remainder of 326.
The next digit of our result is 3. 
Result so far: 67039.50683
Deduct 2634 from 2960 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 14:
878 goes into 3260 3 times with a remainder of 626.
Write down 3 as next digit of the result. 
Result so far: 67039.506833
The remainder is 626 after subtracting 2634 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

The final outcome is 67039.506833, with a leftover of 6.26e-05.
