709890 ÷ 64 
We're looking to find how many times 64 goes into 709890.

Moving on to step 1:
The number 64 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 64

Going ahead to step 2:
64 goes into 70 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 64 from 70 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 64

On to step 3:
When dividing 69 by 64, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 64 away from 69, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 64

Going ahead to step 4:
58 divided by 64 is 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtract 0 from 58 to get 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 64

Going ahead to step 5:
The number 64 fits into 589 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1109.0
Subtracting 576 from 589 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 64

On to step 6:
64 can be fit into 130 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 11092.0
If we take 128 away from 130, 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.

Moving on to step 7:
When dividing 20 by 64, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11092.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
The number 64 fits into 200 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 11092.03
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 64 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 11092.031
If we take 64 away from 80, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 64 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 11092.0312
Deduct 128 from 160 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.

Moving on to step 11:
64 goes into 320 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 11092.03125
Deduct 320 from 320 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11092.03125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11092.03125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11092.03125, with a leftover of 0.0.
