644580 divided by 34 
We want to figure out the number of times 644580 can be divided by 34.

Going ahead to step 1:
34 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 34

Going ahead to step 2:
The number 34 fits into 64 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
If we take 34 away from 64, we end up with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 34

Step 3:
304 divided by 34 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 272 from 304 leaves us with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 34

Let's proceed to step 4:
34 goes into 325 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
Deduct 306 from 325 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 34

On to step 5:
34 goes into 198 5 times with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 1895.0
The remainder is 28 after subtracting 170 from 198.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 34

Let's proceed to step 6:
34 goes into 280 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 18958.0
Subtracting 272 from 280 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
34 can be fit into 80 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 18958.2
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
The number 34 fits into 120 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 18958.23
Subtract 102 from 120 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
34 goes into 180 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 18958.235
If we take 170 away from 180, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 34, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 18958.2352
Deduct 68 from 100 and we're left 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 11:
When dividing 320 by 34, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 18958.23529
Deduct 306 from 320 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.

On to step 12:
34 can be fit into 140 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 18958.235294
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
The number 34 fits into 40 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 18958.2352941
Subtracting 34 from 40 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
60 divided by 34 is 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 18958.23529411
Deduct 34 from 60 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 18958.23529411 with a remaining 2.6e-08.
