64489665 ÷ 712 
We're looking to find how many times 712 goes into 64489665.

Going ahead to step 1:
When dividing 6 by 712, 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 / 712

Going ahead to step 2:
If we divide 64 by 712, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 712

Let's proceed to step 3:
The number 712 fits into 644 0 times, leaving a remainder of 644.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 644 and we're left with 644.
Append the next digit (8) from the dividend to 644 and continue with: 6448 / 712

Going ahead to step 4:
The number 712 fits into 6448 9 times, leaving a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 6408 from 6448 to get 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 712

Advancing to step 5:
If we divide 409 by 712, we get 0 and a remainder of 409.
The next digit of our result is 0. 
Result so far: 90.0
The remainder is 409 after subtracting 0 from 409.
Take the next digit (6) from the dividend and append it to 409, then repeat: 4096 / 712

Step 6:
When dividing 4096 by 712, we get 5 with a remainder of 536.
The next digit of our result is 5. 
Result so far: 905.0
Subtracting 3560 from 4096 leaves us with 536.
Take the next digit (6) from the dividend and append it to 536, then repeat: 5366 / 712

Advancing to step 7:
If we divide 5366 by 712, we get 7 and a remainder of 382.
The number 7 becomes the next digit in our result. 
Result so far: 9057.0
If we subtract 4984 from 5366, we get 382.
Append the next digit (5) from the dividend to 382 and continue with: 3825 / 712

Advancing to step 8:
When dividing 3825 by 712, we get 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 90575.0
Subtracting 3560 from 3825 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 9:
The number 712 fits into 2650 3 times, leaving a remainder of 514.
Use 3 as the next digit of our solution. 
Result so far: 90575.3
If we take 2136 away from 2650, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 10:
When dividing 5140 by 712, we get 7 with a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 90575.37
The remainder is 156 after subtracting 4984 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
If we divide 1560 by 712, we get 2 and a remainder of 136.
Use 2 as the next digit of our solution. 
Result so far: 90575.372
Subtracting 1424 from 1560 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
If we divide 1360 by 712, we get 1 and a remainder of 648.
Write down 1 as next digit of the result. 
Result so far: 90575.3721
Deduct 712 from 1360 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 13:
When dividing 6480 by 712, we get 9 with a remainder of 72.
The next digit of our result is 9. 
Result so far: 90575.37219
If we take 6408 away from 6480, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
When dividing 720 by 712, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 90575.372191
Subtract 712 from 720 to get 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 15:
712 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 90575.372191
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
712 can be fit into 800 1 times, resulting in a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 90575.37219101
Deduct 712 from 800 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 90575.37219101 with a balance of 8.8e-08.
