Let's divide 64391082 by 905
We want to figure out the number of times 64391082 can be divided by 905.

Moving on to step 1:
905 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 905

On to step 2:
The number 905 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 905

Let's proceed to step 3:
When dividing 643 by 905, we get 0 with a remainder of 643.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 643 after subtracting 0 from 643.
Fetch the next digit (9) from the dividend, attach it to 643 and continue: 6439 / 905

Advancing to step 4:
If we divide 6439 by 905, we get 7 and a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 104 after subtracting 6335 from 6439.
Grab the next digit (1) from the dividend, add it to 104, then carry on: 1041 / 905

On to step 5:
905 can be fit into 1041 1 times, resulting in a remainder of 136.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we subtract 905 from 1041, we get 136.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 905

Moving on to step 6:
The number 905 fits into 1360 1 times, leaving a remainder of 455.
Use 1 as the next digit of our solution. 
Result so far: 711.0
Subtracting 905 from 1360 leaves us with 455.
Fetch the next digit (8) from the dividend, attach it to 455 and continue: 4558 / 905

Step 7:
905 goes into 4558 5 times with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 7115.0
Deduct 4525 from 4558 and we're left with 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 905

Advancing to step 8:
905 goes into 332 0 times with a remainder of 332.
Put 0 as the next digit of the answer. 
Result so far: 71150.0
If we take 0 away from 332, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 9:
When dividing 3320 by 905, we get 3 with a remainder of 605.
Write down 3 as next digit of the result. 
Result so far: 71150.3
Deduct 2715 from 3320 and we're left with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 10:
If we divide 6050 by 905, we get 6 and a remainder of 620.
Record the quotient 6 as the next digit in the result. 
Result so far: 71150.36
Subtracting 5430 from 6050 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 11:
The number 905 fits into 6200 6 times, leaving a remainder of 770.
Put 6 as the next digit of the answer. 
Result so far: 71150.366
The remainder is 770 after subtracting 5430 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

The final result is 71150.366 with a remainder of 0.077.
