87421504 ÷ 612 
We want to figure out the number of times 87421504 can be divided by 612.

On to step 1:
If we divide 8 by 612, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 612

Going ahead to step 2:
The number 612 fits into 87 0 times, leaving a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 612

Moving on to step 3:
612 goes into 874 1 times with a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 612 from 874 to get 262.
Bring next digit (2) of the dividend behind the 262 and repeat the process: 2622 / 612

Going ahead to step 4:
2622 divided by 612 is 4 with a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 174 after subtracting 2448 from 2622.
Take the next digit (1) from the dividend and append it to 174, then repeat: 1741 / 612

Going ahead to step 5:
1741 divided by 612 is 2 with a remainder of 517.
The next digit of our result is 2. 
Result so far: 142.0
If we take 1224 away from 1741, we end up with 517.
Include the next digit (5) from the dividend after 517, then repeat: 5175 / 612

Going ahead to step 6:
612 goes into 5175 8 times with a remainder of 279.
The number 8 becomes the next digit in our result. 
Result so far: 1428.0
Deduct 4896 from 5175 and we're left with 279.
Include the next digit (0) from the dividend after 279, then repeat: 2790 / 612

Advancing to step 7:
612 goes into 2790 4 times with a remainder of 342.
The next digit of our result is 4. 
Result so far: 14284.0
If we take 2448 away from 2790, we end up with 342.
Grab the next digit (4) from the dividend, add it to 342, then carry on: 3424 / 612

Step 8:
612 can be fit into 3424 5 times, resulting in a remainder of 364.
Put 5 as the next digit of the answer. 
Result so far: 142845.0
Subtracting 3060 from 3424 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 9:
When dividing 3640 by 612, we get 5 with a remainder of 580.
Put 5 as the next digit of the answer. 
Result so far: 142845.5
Subtracting 3060 from 3640 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 10:
The number 612 fits into 5800 9 times, leaving a remainder of 292.
Use 9 as the next digit of our solution. 
Result so far: 142845.59
The remainder is 292 after subtracting 5508 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 11:
612 can be fit into 2920 4 times, resulting in a remainder of 472.
The next digit of our result is 4. 
Result so far: 142845.594
The remainder is 472 after subtracting 2448 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 12:
612 goes into 4720 7 times with a remainder of 436.
The next digit of our result is 7. 
Result so far: 142845.5947
Subtract 4284 from 4720 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 13:
612 can be fit into 4360 7 times, resulting in a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 142845.59477
Subtract 4284 from 4360 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 142845.59477, and the remainder is 7.6e-05.
