87009638 divided by 486 
We want to figure out the number of times 87009638 can be divided by 486.

Step 1:
If we divide 8 by 486, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 486

On to step 2:
486 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 486

Advancing to step 3:
The number 486 fits into 870 1 times, leaving a remainder of 384.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 384 after subtracting 486 from 870.
Append the next digit (0) from the dividend to 384 and continue with: 3840 / 486

Step 4:
When dividing 3840 by 486, we get 7 with a remainder of 438.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 438 after subtracting 3402 from 3840.
Take the next digit (9) from the dividend and append it to 438, then repeat: 4389 / 486

Let's proceed to step 5:
486 can be fit into 4389 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 179.0
The remainder is 15 after subtracting 4374 from 4389.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 486

On to step 6:
486 can be fit into 156 0 times, resulting in a remainder of 156.
Record the quotient 0 as the next digit in the result. 
Result so far: 1790.0
Subtracting 0 from 156 leaves us with 156.
Bring next digit (3) of the dividend behind the 156 and repeat the process: 1563 / 486

Moving on to step 7:
486 can be fit into 1563 3 times, resulting in a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 17903.0
The remainder is 105 after subtracting 1458 from 1563.
Include the next digit (8) from the dividend after 105, then repeat: 1058 / 486

Step 8:
If we divide 1058 by 486, we get 2 and a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 179032.0
Subtracting 972 from 1058 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
When dividing 860 by 486, we get 1 with a remainder of 374.
Put 1 as the next digit of the answer. 
Result so far: 179032.1
Subtracting 486 from 860 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 10:
3740 divided by 486 is 7 with a remainder of 338.
Put 7 as the next digit of the answer. 
Result so far: 179032.17
Subtracting 3402 from 3740 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 11:
If we divide 3380 by 486, we get 6 and a remainder of 464.
Put 6 as the next digit of the answer. 
Result so far: 179032.176
The remainder is 464 after subtracting 2916 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 12:
If we divide 4640 by 486, we get 9 and a remainder of 266.
Use 9 as the next digit of our solution. 
Result so far: 179032.1769
Subtracting 4374 from 4640 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 13:
486 goes into 2660 5 times with a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 179032.17695
If we take 2430 away from 2660, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
486 can be fit into 2300 4 times, resulting in a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 179032.176954
Subtracting 1944 from 2300 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 15:
The number 486 fits into 3560 7 times, leaving a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 179032.1769547
Subtracting 3402 from 3560 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.

On to step 16:
When dividing 1580 by 486, we get 3 with a remainder of 122.
Put 3 as the next digit of the answer. 
Result so far: 179032.17695473
Subtracting 1458 from 1580 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The quotient of the division is 179032.17695473, and the remainder is 1.22e-07.
