Let's divide 644607 by 86
Let's see how many times 86 fits into 644607.

Let's proceed to step 1:
6 divided by 86 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 86

Let's proceed to step 2:
86 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 86

On to step 3:
If we divide 644 by 86, we get 7 and a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 602 from 644 leaves us with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 86

On to step 4:
The number 86 fits into 426 4 times, leaving a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 344 away from 426, we end up with 82.
Include the next digit (0) from the dividend after 82, then repeat: 820 / 86

Moving on to step 5:
86 can be fit into 820 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 749.0
Subtract 774 from 820 to get 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 86

Step 6:
467 divided by 86 is 5 with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 7495.0
If we subtract 430 from 467, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
When dividing 370 by 86, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7495.4
If we subtract 344 from 370, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 86, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 7495.43
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7495.43
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 7495.4302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 7495.43023
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
When dividing 220 by 86, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 7495.430232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
When dividing 480 by 86, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 7495.4302325
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
86 goes into 500 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7495.43023255
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 7495.43023255, and the remainder is 7e-08.
