87070146 divided by 577 
We want to figure out the number of times 87070146 can be divided by 577.

Moving on to step 1:
When dividing 8 by 577, we get 0 with 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.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 577

Step 2:
The number 577 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 577

Going ahead to step 3:
If we divide 870 by 577, we get 1 and a remainder of 293.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 577 from 870 leaves us with 293.
Include the next digit (7) from the dividend after 293, then repeat: 2937 / 577

Step 4:
When dividing 2937 by 577, we get 5 with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2885 away from 2937, we end up with 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 577

Step 5:
520 divided by 577 is 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
If we take 0 away from 520, we end up with 520.
Fetch the next digit (1) from the dividend, attach it to 520 and continue: 5201 / 577

On to step 6:
577 goes into 5201 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 1509.0
Subtracting 5193 from 5201 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 577

Step 7:
84 divided by 577 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 15090.0
Subtract 0 from 84 to get 84.
Take the next digit (6) from the dividend and append it to 84, then repeat: 846 / 577

Moving on to step 8:
If we divide 846 by 577, we get 1 and a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 150901.0
Subtract 577 from 846 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 9:
577 can be fit into 2690 4 times, resulting in a remainder of 382.
Write down 4 as next digit of the result. 
Result so far: 150901.4
Subtracting 2308 from 2690 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 10:
3820 divided by 577 is 6 with a remainder of 358.
Use 6 as the next digit of our solution. 
Result so far: 150901.46
If we take 3462 away from 3820, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 11:
If we divide 3580 by 577, we get 6 and a remainder of 118.
The next digit of our result is 6. 
Result so far: 150901.466
Deduct 3462 from 3580 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The final outcome is 150901.466, with a leftover of 0.0118.
