Let's divide 86554359 by 387
We want to figure out the number of times 86554359 can be divided by 387.

Let's proceed to step 1:
387 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 387

Step 2:
387 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 387

Advancing to step 3:
When dividing 865 by 387, we get 2 with a remainder of 91.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 774 from 865 to get 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 387

Step 4:
387 goes into 915 2 times with a remainder of 141.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 774 from 915 and we're left with 141.
Fetch the next digit (4) from the dividend, attach it to 141 and continue: 1414 / 387

Advancing to step 5:
387 can be fit into 1414 3 times, resulting in a remainder of 253.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we take 1161 away from 1414, we end up with 253.
Grab the next digit (3) from the dividend, add it to 253, then carry on: 2533 / 387

Let's proceed to step 6:
387 goes into 2533 6 times with a remainder of 211.
Put 6 as the next digit of the answer. 
Result so far: 2236.0
Deduct 2322 from 2533 and we're left with 211.
Fetch the next digit (5) from the dividend, attach it to 211 and continue: 2115 / 387

Moving on to step 7:
When dividing 2115 by 387, we get 5 with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 22365.0
The remainder is 180 after subtracting 1935 from 2115.
Take the next digit (9) from the dividend and append it to 180, then repeat: 1809 / 387

On to step 8:
If we divide 1809 by 387, we get 4 and a remainder of 261.
The number 4 becomes the next digit in our result. 
Result so far: 223654.0
Subtract 1548 from 1809 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 9:
387 goes into 2610 6 times with a remainder of 288.
The next digit of our result is 6. 
Result so far: 223654.6
If we subtract 2322 from 2610, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 10:
The number 387 fits into 2880 7 times, leaving a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 223654.67
If we take 2709 away from 2880, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 11:
1710 divided by 387 is 4 with a remainder of 162.
The number 4 becomes the next digit in our result. 
Result so far: 223654.674
Subtracting 1548 from 1710 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 12:
387 goes into 1620 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 223654.6744
Subtracting 1548 from 1620 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 223654.6744, and the remainder is 0.00072.
