87239480 divided by 612 
Our goal is to divide 87239480 by 612.

Step 1:
612 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 612

Moving on to step 2:
612 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 612

Advancing to step 3:
The number 612 fits into 872 1 times, leaving a remainder of 260.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 612 from 872 and we're left with 260.
Include the next digit (3) from the dividend after 260, then repeat: 2603 / 612

Let's proceed to step 4:
612 goes into 2603 4 times with a remainder of 155.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2448 from 2603 and we're left with 155.
Bring next digit (9) of the dividend behind the 155 and repeat the process: 1559 / 612

Going ahead to step 5:
When dividing 1559 by 612, we get 2 with a remainder of 335.
Write down 2 as next digit of the result. 
Result so far: 142.0
Deduct 1224 from 1559 and we're left with 335.
Grab the next digit (4) from the dividend, add it to 335, then carry on: 3354 / 612

Going ahead to step 6:
If we divide 3354 by 612, we get 5 and a remainder of 294.
The next digit of our result is 5. 
Result so far: 1425.0
Deduct 3060 from 3354 and we're left with 294.
Fetch the next digit (8) from the dividend, attach it to 294 and continue: 2948 / 612

Step 7:
When dividing 2948 by 612, we get 4 with a remainder of 500.
The next digit of our result is 4. 
Result so far: 14254.0
If we take 2448 away from 2948, we end up with 500.
Bring next digit (0) of the dividend behind the 500 and repeat the process: 5000 / 612

Let's proceed to step 8:
When dividing 5000 by 612, we get 8 with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 142548.0
Deduct 4896 from 5000 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 9:
612 goes into 1040 1 times with a remainder of 428.
The number 1 becomes the next digit in our result. 
Result so far: 142548.1
If we subtract 612 from 1040, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 10:
612 can be fit into 4280 6 times, resulting in a remainder of 608.
Record the quotient 6 as the next digit in the result. 
Result so far: 142548.16
Deduct 3672 from 4280 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 11:
612 goes into 6080 9 times with a remainder of 572.
Write down 9 as next digit of the result. 
Result so far: 142548.169
Subtract 5508 from 6080 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Moving on to step 12:
The number 612 fits into 5720 9 times, leaving a remainder of 212.
The number 9 becomes the next digit in our result. 
Result so far: 142548.1699
Subtracting 5508 from 5720 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 142548.1699 with a remainder of 0.00212.
