621887 ÷ 87 
Let's see how many times 87 fits into 621887.

On to step 1:
6 divided by 87 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 87

Step 2:
87 goes into 62 0 times with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 87

Let's proceed to step 3:
87 can be fit into 621 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 609 from 621 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 87

Going ahead to step 4:
87 can be fit into 128 1 times, resulting in a remainder of 41.
The next digit of our result is 1. 
Result so far: 71.0
Deduct 87 from 128 and we're left with 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 87

Step 5:
418 divided by 87 is 4 with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 714.0
Subtracting 348 from 418 leaves us with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 87

On to step 6:
If we divide 707 by 87, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 7148.0
The remainder is 11 after subtracting 696 from 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 87, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 7148.1
Subtracting 87 from 110 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
If we divide 230 by 87, we get 2 and a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 7148.12
Subtract 174 from 230 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
87 can be fit into 560 6 times, resulting in a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 7148.126
The remainder is 38 after subtracting 522 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
When dividing 380 by 87, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7148.1264
If we take 348 away from 380, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
87 can be fit into 320 3 times, resulting in a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 7148.12643
Deduct 261 from 320 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 12:
If we divide 590 by 87, we get 6 and a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 7148.126436
If we subtract 522 from 590, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
680 divided by 87 is 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 7148.1264367
If we take 609 away from 680, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 14:
The number 87 fits into 710 8 times, leaving a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 7148.12643678
Deduct 696 from 710 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 7148.12643678 with a balance of 1.4e-08.
