We're dividing 621555 by 87 
We want to divide 621555 by 87.

Step 1:
87 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 87

Advancing to step 2:
If we divide 62 by 87, we get 0 and a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 87

Going ahead to step 3:
When dividing 621 by 87, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 609 from 621 leaves us with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 87

Let's proceed to step 4:
When dividing 125 by 87, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 87 away from 125, we end up with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 87

Let's proceed to step 5:
87 can be fit into 385 4 times, resulting in a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 714.0
The remainder is 37 after subtracting 348 from 385.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 87

On to step 6:
375 divided by 87 is 4 with a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 7144.0
Subtract 348 from 375 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 87, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 7144.3
If we take 261 away from 270, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
87 can be fit into 90 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7144.31
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
87 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 7144.31
If we subtract 0 from 30, we 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.

Going ahead to step 10:
When dividing 300 by 87, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 7144.3103
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
87 goes into 390 4 times with a remainder of 42.
The next digit of our result is 4. 
Result so far: 7144.31034
If we take 348 away from 390, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
When dividing 420 by 87, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 7144.310344
If we take 348 away from 420, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 7144.310344, and the remainder is 7.2e-06.
