We look at the division of 81612977 by 870 
We're looking to find how many times 870 goes into 81612977.

Moving on to step 1:
870 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 870

On to step 2:
When dividing 81 by 870, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 870

On to step 3:
The number 870 fits into 816 0 times, leaving a remainder of 816.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 816 to get 816.
Append the next digit (1) from the dividend to 816 and continue with: 8161 / 870

Advancing to step 4:
The number 870 fits into 8161 9 times, leaving a remainder of 331.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7830 away from 8161, we end up with 331.
Fetch the next digit (2) from the dividend, attach it to 331 and continue: 3312 / 870

Advancing to step 5:
870 can be fit into 3312 3 times, resulting in a remainder of 702.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we take 2610 away from 3312, we end up with 702.
Take the next digit (9) from the dividend and append it to 702, then repeat: 7029 / 870

Let's proceed to step 6:
The number 870 fits into 7029 8 times, leaving a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 938.0
The remainder is 69 after subtracting 6960 from 7029.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 870

Going ahead to step 7:
697 divided by 870 is 0 with a remainder of 697.
Use 0 as the next digit of our solution. 
Result so far: 9380.0
Deduct 0 from 697 and we're left with 697.
Take the next digit (7) from the dividend and append it to 697, then repeat: 6977 / 870

On to step 8:
When dividing 6977 by 870, we get 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 93808.0
The remainder is 17 after subtracting 6960 from 6977.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
870 can be fit into 170 0 times, resulting in a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 93808.0
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
If we divide 1700 by 870, we get 1 and a remainder of 830.
Put 1 as the next digit of the answer. 
Result so far: 93808.01
Subtracting 870 from 1700 leaves us with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

On to step 11:
870 can be fit into 8300 9 times, resulting in a remainder of 470.
Put 9 as the next digit of the answer. 
Result so far: 93808.019
If we take 7830 away from 8300, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 12:
4700 divided by 870 is 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 93808.0195
The remainder is 350 after subtracting 4350 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
3500 divided by 870 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 93808.01954
Subtracting 3480 from 3500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
870 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 93808.01954
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
The number 870 fits into 2000 2 times, leaving a remainder of 260.
The next digit of our result is 2. 
Result so far: 93808.0195402
Subtracting 1740 from 2000 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 16:
870 goes into 2600 2 times with a remainder of 860.
The next digit of our result is 2. 
Result so far: 93808.01954022
Subtract 1740 from 2600 to get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The quotient of the division is 93808.01954022, and the remainder is 8.6e-07.
