We're dividing 87210157 by 813 
Let's see how many times 813 fits into 87210157.

Moving on to step 1:
8 divided by 813 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 813

Moving on to step 2:
813 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 813

Advancing to step 3:
872 divided by 813 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 813 from 872 to get 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 813

On to step 4:
591 divided by 813 is 0 with a remainder of 591.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 591 and we're left with 591.
Include the next digit (0) from the dividend after 591, then repeat: 5910 / 813

Step 5:
813 goes into 5910 7 times with a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we subtract 5691 from 5910, we get 219.
Take the next digit (1) from the dividend and append it to 219, then repeat: 2191 / 813

On to step 6:
When dividing 2191 by 813, we get 2 with a remainder of 565.
The next digit of our result is 2. 
Result so far: 1072.0
If we subtract 1626 from 2191, we get 565.
Bring next digit (5) of the dividend behind the 565 and repeat the process: 5655 / 813

Advancing to step 7:
5655 divided by 813 is 6 with a remainder of 777.
Write down 6 as next digit of the result. 
Result so far: 10726.0
Subtract 4878 from 5655 to get 777.
Fetch the next digit (7) from the dividend, attach it to 777 and continue: 7777 / 813

Step 8:
If we divide 7777 by 813, we get 9 and a remainder of 460.
Use 9 as the next digit of our solution. 
Result so far: 107269.0
Subtract 7317 from 7777 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 9:
If we divide 4600 by 813, we get 5 and a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 107269.5
The remainder is 535 after subtracting 4065 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Let's proceed to step 10:
813 can be fit into 5350 6 times, resulting in a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 107269.56
Subtract 4878 from 5350 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 11:
When dividing 4720 by 813, we get 5 with a remainder of 655.
The next digit of our result is 5. 
Result so far: 107269.565
If we take 4065 away from 4720, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Let's proceed to step 12:
813 can be fit into 6550 8 times, resulting in a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 107269.5658
If we take 6504 away from 6550, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
The number 813 fits into 460 0 times, leaving a remainder of 460.
The next digit of our result is 0. 
Result so far: 107269.5658
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 14:
If we divide 4600 by 813, we get 5 and a remainder of 535.
Record the quotient 5 as the next digit in the result. 
Result so far: 107269.565805
If we subtract 4065 from 4600, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Step 15:
5350 divided by 813 is 6 with a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 107269.5658056
If we take 4878 away from 5350, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 16:
813 can be fit into 4720 5 times, resulting in a remainder of 655.
The next digit of our result is 5. 
Result so far: 107269.56580565
If we subtract 4065 from 4720, we get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

The final result is 107269.56580565 with a remainder of 6.55e-07.
