89118564 ÷ 387 
We want to divide 89118564 by 387.

Advancing to step 1:
8 divided by 387 is 0 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 (9) from the dividend, attach it to 8 and continue: 89 / 387

Step 2:
When dividing 89 by 387, we get 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 387

Step 3:
891 divided by 387 is 2 with a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 774 from 891 and we're left with 117.
Append the next digit (1) from the dividend to 117 and continue with: 1171 / 387

Step 4:
If we divide 1171 by 387, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 10 after subtracting 1161 from 1171.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 387

Let's proceed to step 5:
387 can be fit into 108 0 times, resulting in a remainder of 108.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Subtract 0 from 108 to get 108.
Bring next digit (5) of the dividend behind the 108 and repeat the process: 1085 / 387

Advancing to step 6:
The number 387 fits into 1085 2 times, leaving a remainder of 311.
Use 2 as the next digit of our solution. 
Result so far: 2302.0
If we take 774 away from 1085, we end up with 311.
Append the next digit (6) from the dividend to 311 and continue with: 3116 / 387

Going ahead to step 7:
When dividing 3116 by 387, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 23028.0
If we take 3096 away from 3116, we end up with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 387

Step 8:
The number 387 fits into 204 0 times, leaving a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 230280.0
If we take 0 away from 204, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 9:
The number 387 fits into 2040 5 times, leaving a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 230280.5
The remainder is 105 after subtracting 1935 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 10:
If we divide 1050 by 387, we get 2 and a remainder of 276.
Write down 2 as next digit of the result. 
Result so far: 230280.52
The remainder is 276 after subtracting 774 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
387 can be fit into 2760 7 times, resulting in a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 230280.527
If we take 2709 away from 2760, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 12:
387 can be fit into 510 1 times, resulting in a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 230280.5271
Subtract 387 from 510 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 13:
If we divide 1230 by 387, we get 3 and a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 230280.52713
If we take 1161 away from 1230, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
The number 387 fits into 690 1 times, leaving a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 230280.527131
If we take 387 away from 690, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 15:
The number 387 fits into 3030 7 times, leaving a remainder of 321.
The number 7 becomes the next digit in our result. 
Result so far: 230280.5271317
Subtracting 2709 from 3030 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 16:
When dividing 3210 by 387, we get 8 with a remainder of 114.
The next digit of our result is 8. 
Result so far: 230280.52713178
Subtract 3096 from 3210 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

After the division, we end up with 230280.52713178 and a remainder of 1.14e-07.
