644906 divided by 87 
Our goal is to divide 644906 by 87.

Going ahead to step 1:
When dividing 6 by 87, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 87

Advancing to step 2:
When dividing 64 by 87, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 87

Going ahead to step 3:
87 can be fit into 644 7 times, resulting in a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 609 from 644 leaves us with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 87

Let's proceed to step 4:
If we divide 359 by 87, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 74.0
The remainder is 11 after subtracting 348 from 359.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 87

On to step 5:
When dividing 110 by 87, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 741.0
The remainder is 23 after subtracting 87 from 110.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 87

Moving on to step 6:
If we divide 236 by 87, we get 2 and a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 7412.0
If we take 174 away from 236, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
If we divide 620 by 87, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7412.7
Subtract 609 from 620 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
When dividing 110 by 87, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 7412.71
If we subtract 87 from 110, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
230 divided by 87 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 7412.712
If we take 174 away from 230, we end up with 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 10:
560 divided by 87 is 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 7412.7126
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.

Advancing to step 11:
87 can be fit into 380 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7412.71264
Subtracting 348 from 380 leaves us 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.

Going ahead to step 12:
The number 87 fits into 320 3 times, leaving a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 7412.712643
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 13:
87 can be fit into 590 6 times, resulting in a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 7412.7126436
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 14:
680 divided by 87 is 7 with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 7412.71264367
The remainder is 71 after subtracting 609 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 7412.71264367 with a balance of 7.1e-08.
