We're dividing 87852438 by 820 
We're looking to find how many times 820 goes into 87852438.

Moving on to step 1:
If we divide 8 by 820, we get 0 and 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:
87 divided by 820 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (8) from the dividend, add it to 87, then carry on: 878 / 820

Advancing to step 3:
When dividing 878 by 820, we get 1 with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 820 from 878, we get 58.
Grab the next digit (5) from the dividend, add it to 58, then carry on: 585 / 820

Let's proceed to step 4:
The number 820 fits into 585 0 times, leaving a remainder of 585.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 585 after subtracting 0 from 585.
Grab the next digit (2) from the dividend, add it to 585, then carry on: 5852 / 820

On to step 5:
820 can be fit into 5852 7 times, resulting in a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 112 after subtracting 5740 from 5852.
Take the next digit (4) from the dividend and append it to 112, then repeat: 1124 / 820

On to step 6:
820 goes into 1124 1 times with a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 1071.0
Subtracting 820 from 1124 leaves us with 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 820

Moving on to step 7:
The number 820 fits into 3043 3 times, leaving a remainder of 583.
Write down 3 as next digit of the result. 
Result so far: 10713.0
Subtracting 2460 from 3043 leaves us with 583.
Grab the next digit (8) from the dividend, add it to 583, then carry on: 5838 / 820

Going ahead to step 8:
When dividing 5838 by 820, we get 7 with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 107137.0
Subtracting 5740 from 5838 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 9:
The number 820 fits into 980 1 times, leaving a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 107137.1
If we subtract 820 from 980, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
820 can be fit into 1600 1 times, resulting in a remainder of 780.
The next digit of our result is 1. 
Result so far: 107137.11
Subtracting 820 from 1600 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Our division results in 107137.11 with a remaining 0.78.
