We look at the division of 87136020 by 820 
Let's see how many times 820 fits into 87136020.

On to step 1:
820 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 820

Let's proceed to step 2:
The number 820 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
If we take 0 away from 87, we end up with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 820

Advancing to step 3:
The number 820 fits into 871 1 times, leaving a remainder of 51.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 820 from 871 leaves us with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 820

Step 4:
The number 820 fits into 513 0 times, leaving a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 513 after subtracting 0 from 513.
Bring next digit (6) of the dividend behind the 513 and repeat the process: 5136 / 820

Going ahead to step 5:
The number 820 fits into 5136 6 times, leaving a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 106.0
If we take 4920 away from 5136, we end up with 216.
Include the next digit (0) from the dividend after 216, then repeat: 2160 / 820

On to step 6:
820 goes into 2160 2 times with a remainder of 520.
Write down 2 as next digit of the result. 
Result so far: 1062.0
If we subtract 1640 from 2160, we get 520.
Include the next digit (2) from the dividend after 520, then repeat: 5202 / 820

Moving on to step 7:
820 goes into 5202 6 times with a remainder of 282.
Put 6 as the next digit of the answer. 
Result so far: 10626.0
If we take 4920 away from 5202, we end up with 282.
Include the next digit (0) from the dividend after 282, then repeat: 2820 / 820

Going ahead to step 8:
If we divide 2820 by 820, we get 3 and a remainder of 360.
Use 3 as the next digit of our solution. 
Result so far: 106263.0
Subtracting 2460 from 2820 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 9:
820 can be fit into 3600 4 times, resulting in a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 106263.4
The remainder is 320 after subtracting 3280 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
When dividing 3200 by 820, we get 3 with a remainder of 740.
Use 3 as the next digit of our solution. 
Result so far: 106263.43
Subtract 2460 from 3200 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 11:
The number 820 fits into 7400 9 times, leaving a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 106263.439
Subtract 7380 from 7400 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
820 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 106263.439
If we subtract 0 from 200, we get 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 13:
The number 820 fits into 2000 2 times, leaving a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 106263.43902
Deduct 1640 from 2000 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 14:
If we divide 3600 by 820, we get 4 and a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 106263.439024
If we subtract 3280 from 3600, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
When dividing 3200 by 820, we get 3 with a remainder of 740.
The number 3 becomes the next digit in our result. 
Result so far: 106263.4390243
Subtracting 2460 from 3200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 16:
820 goes into 7400 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 106263.43902439
If we take 7380 away from 7400, we end up 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.

After the division, we end up with 106263.43902439 and a remainder of 2e-08.
