We look at the division of 87781 by 58 
We're looking to find how many times 58 goes into 87781.

On to step 1:
58 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 58

Step 2:
58 can be fit into 87 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 58 from 87, we get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 58

Step 3:
297 divided by 58 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 290 away from 297, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 58

Moving on to step 4:
The number 58 fits into 78 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 151.0
Deduct 58 from 78 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 58

Moving on to step 5:
58 can be fit into 201 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 1513.0
If we take 174 away from 201, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 6:
If we divide 270 by 58, we get 4 and a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 1513.4
The remainder is 38 after subtracting 232 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
When dividing 380 by 58, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1513.46
Deduct 348 from 380 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
58 goes into 320 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1513.465
If we subtract 290 from 320, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
If we divide 300 by 58, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 1513.4655
If we take 290 away from 300, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 1513.4655 with a remaining 0.0001.
