87712777 ÷ 958 
Our goal is to divide 87712777 by 958.

Going ahead to step 1:
958 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 958

Let's proceed to step 2:
The number 958 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 958

Going ahead to step 3:
958 goes into 877 0 times with a remainder of 877.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 877 after subtracting 0 from 877.
Grab the next digit (1) from the dividend, add it to 877, then carry on: 8771 / 958

Let's proceed to step 4:
958 can be fit into 8771 9 times, resulting in a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 8622 from 8771 leaves us with 149.
Include the next digit (2) from the dividend after 149, then repeat: 1492 / 958

Advancing to step 5:
958 goes into 1492 1 times with a remainder of 534.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 958 from 1492, we get 534.
Append the next digit (7) from the dividend to 534 and continue with: 5347 / 958

Step 6:
When dividing 5347 by 958, we get 5 with a remainder of 557.
The next digit of our result is 5. 
Result so far: 915.0
If we take 4790 away from 5347, we end up with 557.
Take the next digit (7) from the dividend and append it to 557, then repeat: 5577 / 958

Step 7:
958 can be fit into 5577 5 times, resulting in a remainder of 787.
The next digit of our result is 5. 
Result so far: 9155.0
If we take 4790 away from 5577, we end up with 787.
Include the next digit (7) from the dividend after 787, then repeat: 7877 / 958

On to step 8:
7877 divided by 958 is 8 with a remainder of 213.
Write down 8 as next digit of the result. 
Result so far: 91558.0
The remainder is 213 after subtracting 7664 from 7877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 9:
The number 958 fits into 2130 2 times, leaving a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 91558.2
Subtracting 1916 from 2130 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 10:
2140 divided by 958 is 2 with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 91558.22
Deduct 1916 from 2140 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 91558.22 with a remainder of 0.224.
