85011887 ÷ 861 
We want to figure out the number of times 85011887 can be divided by 861.

Advancing to step 1:
If we divide 8 by 861, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 861

Let's proceed to step 2:
85 divided by 861 is 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 861

Moving on to step 3:
When dividing 850 by 861, we get 0 with a remainder of 850.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 850, we end up with 850.
Append the next digit (1) from the dividend to 850 and continue with: 8501 / 861

Moving on to step 4:
861 can be fit into 8501 9 times, resulting in a remainder of 752.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7749 from 8501 and we're left with 752.
Fetch the next digit (1) from the dividend, attach it to 752 and continue: 7521 / 861

Advancing to step 5:
If we divide 7521 by 861, we get 8 and a remainder of 633.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 6888 from 7521 leaves us with 633.
Fetch the next digit (8) from the dividend, attach it to 633 and continue: 6338 / 861

Step 6:
If we divide 6338 by 861, we get 7 and a remainder of 311.
Use 7 as the next digit of our solution. 
Result so far: 987.0
The remainder is 311 after subtracting 6027 from 6338.
Append the next digit (8) from the dividend to 311 and continue with: 3118 / 861

Going ahead to step 7:
When dividing 3118 by 861, we get 3 with a remainder of 535.
The next digit of our result is 3. 
Result so far: 9873.0
If we take 2583 away from 3118, we end up with 535.
Fetch the next digit (7) from the dividend, attach it to 535 and continue: 5357 / 861

Going ahead to step 8:
861 can be fit into 5357 6 times, resulting in a remainder of 191.
Use 6 as the next digit of our solution. 
Result so far: 98736.0
Subtract 5166 from 5357 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 9:
When dividing 1910 by 861, we get 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 98736.2
If we take 1722 away from 1910, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 10:
The number 861 fits into 1880 2 times, leaving a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 98736.22
Subtracting 1722 from 1880 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The quotient of the division is 98736.22, and the remainder is 0.158.
