We're dividing 81243977 by 887 
We want to figure out the number of times 81243977 can be divided by 887.

Moving on to step 1:
If we divide 8 by 887, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 887

Going ahead to step 2:
887 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 887

Let's proceed to step 3:
The number 887 fits into 812 0 times, leaving a remainder of 812.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 812 and we're left with 812.
Take the next digit (4) from the dividend and append it to 812, then repeat: 8124 / 887

On to step 4:
887 goes into 8124 9 times with a remainder of 141.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7983 away from 8124, we end up with 141.
Grab the next digit (3) from the dividend, add it to 141, then carry on: 1413 / 887

On to step 5:
If we divide 1413 by 887, we get 1 and a remainder of 526.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtracting 887 from 1413 leaves us with 526.
Grab the next digit (9) from the dividend, add it to 526, then carry on: 5269 / 887

Moving on to step 6:
887 can be fit into 5269 5 times, resulting in a remainder of 834.
Use 5 as the next digit of our solution. 
Result so far: 915.0
Subtract 4435 from 5269 to get 834.
Append the next digit (7) from the dividend to 834 and continue with: 8347 / 887

Let's proceed to step 7:
If we divide 8347 by 887, we get 9 and a remainder of 364.
The next digit of our result is 9. 
Result so far: 9159.0
Deduct 7983 from 8347 and we're left with 364.
Include the next digit (7) from the dividend after 364, then repeat: 3647 / 887

Step 8:
If we divide 3647 by 887, we get 4 and a remainder of 99.
Put 4 as the next digit of the answer. 
Result so far: 91594.0
Subtracting 3548 from 3647 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
If we divide 990 by 887, we get 1 and a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 91594.1
Deduct 887 from 990 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 10:
The number 887 fits into 1030 1 times, leaving a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 91594.11
Subtracting 887 from 1030 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The quotient of the division is 91594.11, and the remainder is 0.143.
