87307189 divided by 861 
Let's see how many times 861 fits into 87307189.

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
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 861

Advancing to step 2:
861 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (3) from the dividend after 87, then repeat: 873 / 861

Going ahead to step 3:
The number 861 fits into 873 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 861 from 873 leaves us with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 861

Let's proceed to step 4:
The number 861 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 120 after subtracting 0 from 120.
Bring next digit (7) of the dividend behind the 120 and repeat the process: 1207 / 861

Step 5:
The number 861 fits into 1207 1 times, leaving a remainder of 346.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we subtract 861 from 1207, we get 346.
Append the next digit (1) from the dividend to 346 and continue with: 3461 / 861

Advancing to step 6:
3461 divided by 861 is 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 1014.0
Subtracting 3444 from 3461 leaves us with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 861

Moving on to step 7:
178 divided by 861 is 0 with a remainder of 178.
The next digit of our result is 0. 
Result so far: 10140.0
The remainder is 178 after subtracting 0 from 178.
Take the next digit (9) from the dividend and append it to 178, then repeat: 1789 / 861

Going ahead to step 8:
When dividing 1789 by 861, we get 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 101402.0
Deduct 1722 from 1789 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
The number 861 fits into 670 0 times, leaving a remainder of 670.
Put 0 as the next digit of the answer. 
Result so far: 101402.0
Subtract 0 from 670 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 10:
6700 divided by 861 is 7 with a remainder of 673.
The number 7 becomes the next digit in our result. 
Result so far: 101402.07
If we take 6027 away from 6700, we end up with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

On to step 11:
When dividing 6730 by 861, we get 7 with a remainder of 703.
Use 7 as the next digit of our solution. 
Result so far: 101402.077
Subtracting 6027 from 6730 leaves us with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

In conclusion, the division gives 101402.077 with a balance of 0.0703.
