64604121 ÷ 710 
Let's see how many times 710 fits into 64604121.

On to step 1:
When dividing 6 by 710, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 710

Going ahead to step 2:
64 divided by 710 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 710

Going ahead to step 3:
646 divided by 710 is 0 with a remainder of 646.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 646, we end up with 646.
Include the next digit (0) from the dividend after 646, then repeat: 6460 / 710

On to step 4:
6460 divided by 710 is 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 6390 from 6460, we get 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 710

Advancing to step 5:
If we divide 704 by 710, we get 0 and a remainder of 704.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 704 after subtracting 0 from 704.
Fetch the next digit (1) from the dividend, attach it to 704 and continue: 7041 / 710

Moving on to step 6:
The number 710 fits into 7041 9 times, leaving a remainder of 651.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Deduct 6390 from 7041 and we're left with 651.
Grab the next digit (2) from the dividend, add it to 651, then carry on: 6512 / 710

Let's proceed to step 7:
The number 710 fits into 6512 9 times, leaving a remainder of 122.
The next digit of our result is 9. 
Result so far: 9099.0
Subtract 6390 from 6512 to get 122.
Append the next digit (1) from the dividend to 122 and continue with: 1221 / 710

On to step 8:
1221 divided by 710 is 1 with a remainder of 511.
Put 1 as the next digit of the answer. 
Result so far: 90991.0
If we take 710 away from 1221, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Advancing to step 9:
The number 710 fits into 5110 7 times, leaving a remainder of 140.
The number 7 becomes the next digit in our result. 
Result so far: 90991.7
If we take 4970 away from 5110, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 710 fits into 1400 1 times, leaving a remainder of 690.
The number 1 becomes the next digit in our result. 
Result so far: 90991.71
If we subtract 710 from 1400, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 11:
If we divide 6900 by 710, we get 9 and a remainder of 510.
Put 9 as the next digit of the answer. 
Result so far: 90991.719
Deduct 6390 from 6900 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 12:
710 goes into 5100 7 times with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 90991.7197
If we subtract 4970 from 5100, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 13:
When dividing 1300 by 710, we get 1 with a remainder of 590.
Record the quotient 1 as the next digit in the result. 
Result so far: 90991.71971
Subtracting 710 from 1300 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 14:
When dividing 5900 by 710, we get 8 with a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 90991.719718
If we take 5680 away from 5900, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
2200 divided by 710 is 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 90991.7197183
If we take 2130 away from 2200, 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.

Let's proceed to step 16:
If we divide 700 by 710, we get 0 and a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 90991.7197183
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

In conclusion, the division gives 90991.7197183 with a balance of 7e-07.
