We're dividing 87357900 by 215 
We want to divide 87357900 by 215.

On to step 1:
When dividing 8 by 215, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 215

Advancing to step 2:
215 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
Subtract 0 from 87 to get 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 215

Going ahead to step 3:
215 can be fit into 873 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 860 from 873 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 215

Advancing to step 4:
135 divided by 215 is 0 with a remainder of 135.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 135, we end up with 135.
Bring next digit (7) of the dividend behind the 135 and repeat the process: 1357 / 215

Step 5:
215 goes into 1357 6 times with a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 406.0
Deduct 1290 from 1357 and we're left with 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 215

On to step 6:
The number 215 fits into 679 3 times, leaving a remainder of 34.
The next digit of our result is 3. 
Result so far: 4063.0
Subtracting 645 from 679 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 215

Step 7:
215 goes into 340 1 times with a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 40631.0
Deduct 215 from 340 and we're left with 125.
Append the next digit (0) from the dividend to 125 and continue with: 1250 / 215

Going ahead to step 8:
If we divide 1250 by 215, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 406315.0
If we subtract 1075 from 1250, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 9:
215 goes into 1750 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 406315.8
Subtract 1720 from 1750 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
215 goes into 300 1 times with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 406315.81
Subtract 215 from 300 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
If we divide 850 by 215, we get 3 and a remainder of 205.
Record the quotient 3 as the next digit in the result. 
Result so far: 406315.813
The remainder is 205 after subtracting 645 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 12:
2050 divided by 215 is 9 with a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 406315.8139
If we subtract 1935 from 2050, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 13:
215 goes into 1150 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 406315.81395
Subtracting 1075 from 1150 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
215 can be fit into 750 3 times, resulting in a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 406315.813953
Deduct 645 from 750 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 15:
215 goes into 1050 4 times with a remainder of 190.
Record the quotient 4 as the next digit in the result. 
Result so far: 406315.8139534
Subtracting 860 from 1050 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 16:
The number 215 fits into 1900 8 times, leaving a remainder of 180.
The next digit of our result is 8. 
Result so far: 406315.81395348
Subtract 1720 from 1900 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 406315.81395348, with a leftover of 1.8e-07.
