We divide 87391189 by 285
We want to divide 87391189 by 285.

Advancing to step 1:
8 divided by 285 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 285

Advancing to step 2:
When dividing 87 by 285, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (3) from the dividend after 87, then repeat: 873 / 285

Going ahead to step 3:
873 divided by 285 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 855 from 873, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 285

On to step 4:
285 can be fit into 189 0 times, resulting in a remainder of 189.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 189 leaves us with 189.
Take the next digit (1) from the dividend and append it to 189, then repeat: 1891 / 285

Let's proceed to step 5:
285 goes into 1891 6 times with a remainder of 181.
Write down 6 as next digit of the result. 
Result so far: 306.0
Subtract 1710 from 1891 to get 181.
Grab the next digit (1) from the dividend, add it to 181, then carry on: 1811 / 285

Let's proceed to step 6:
The number 285 fits into 1811 6 times, leaving a remainder of 101.
Put 6 as the next digit of the answer. 
Result so far: 3066.0
Deduct 1710 from 1811 and we're left with 101.
Fetch the next digit (8) from the dividend, attach it to 101 and continue: 1018 / 285

Going ahead to step 7:
If we divide 1018 by 285, we get 3 and a remainder of 163.
The next digit of our result is 3. 
Result so far: 30663.0
If we take 855 away from 1018, we end up with 163.
Fetch the next digit (9) from the dividend, attach it to 163 and continue: 1639 / 285

Step 8:
285 can be fit into 1639 5 times, resulting in a remainder of 214.
Record the quotient 5 as the next digit in the result. 
Result so far: 306635.0
Subtract 1425 from 1639 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 9:
2140 divided by 285 is 7 with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 306635.7
Subtracting 1995 from 2140 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
When dividing 1450 by 285, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 306635.75
Subtract 1425 from 1450 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
285 goes into 250 0 times with a remainder of 250.
The next digit of our result is 0. 
Result so far: 306635.75
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
The number 285 fits into 2500 8 times, leaving a remainder of 220.
The next digit of our result is 8. 
Result so far: 306635.7508
Deduct 2280 from 2500 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
When dividing 2200 by 285, we get 7 with a remainder of 205.
The next digit of our result is 7. 
Result so far: 306635.75087
If we subtract 1995 from 2200, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 14:
2050 divided by 285 is 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 306635.750877
Subtracting 1995 from 2050 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 306635.750877, with a leftover of 5.5e-06.
