64423770 ÷ 710 
We're looking to find how many times 710 goes into 64423770.

Going ahead to step 1:
When dividing 6 by 710, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 710

Moving on to step 2:
When dividing 64 by 710, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 710

Moving on to step 3:
When dividing 644 by 710, we get 0 with a remainder of 644.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 644 after subtracting 0 from 644.
Bring next digit (2) of the dividend behind the 644 and repeat the process: 6442 / 710

Advancing to step 4:
If we divide 6442 by 710, we get 9 and a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 6390 away from 6442, we end up with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 710

Moving on to step 5:
523 divided by 710 is 0 with a remainder of 523.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 523 and we're left with 523.
Grab the next digit (7) from the dividend, add it to 523, then carry on: 5237 / 710

Moving on to step 6:
When dividing 5237 by 710, we get 7 with a remainder of 267.
Record the quotient 7 as the next digit in the result. 
Result so far: 907.0
Subtract 4970 from 5237 to get 267.
Grab the next digit (7) from the dividend, add it to 267, then carry on: 2677 / 710

On to step 7:
The number 710 fits into 2677 3 times, leaving a remainder of 547.
Record the quotient 3 as the next digit in the result. 
Result so far: 9073.0
Subtracting 2130 from 2677 leaves us with 547.
Take the next digit (0) from the dividend and append it to 547, then repeat: 5470 / 710

On to step 8:
710 can be fit into 5470 7 times, resulting in a remainder of 500.
Use 7 as the next digit of our solution. 
Result so far: 90737.0
Subtract 4970 from 5470 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 9:
If we divide 5000 by 710, we get 7 and a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 90737.7
If we take 4970 away from 5000, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
The number 710 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 90737.7
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
If we divide 3000 by 710, we get 4 and a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 90737.704
The remainder is 160 after subtracting 2840 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
If we divide 1600 by 710, we get 2 and a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 90737.7042
Subtract 1420 from 1600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 13:
If we divide 1800 by 710, we get 2 and a remainder of 380.
The number 2 becomes the next digit in our result. 
Result so far: 90737.70422
If we subtract 1420 from 1800, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 90737.70422 with a remaining 0.00038.
