70635439 ÷ 647 
We want to figure out the number of times 70635439 can be divided by 647.

Step 1:
647 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 647

Going ahead to step 2:
70 divided by 647 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 647

Step 3:
If we divide 706 by 647, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 647 from 706 to get 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 647

Advancing to step 4:
When dividing 593 by 647, we get 0 with a remainder of 593.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 593, we get 593.
Take the next digit (5) from the dividend and append it to 593, then repeat: 5935 / 647

On to step 5:
When dividing 5935 by 647, we get 9 with a remainder of 112.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Subtract 5823 from 5935 to get 112.
Bring next digit (4) of the dividend behind the 112 and repeat the process: 1124 / 647

Moving on to step 6:
The number 647 fits into 1124 1 times, leaving a remainder of 477.
Use 1 as the next digit of our solution. 
Result so far: 1091.0
Subtract 647 from 1124 to get 477.
Bring next digit (3) of the dividend behind the 477 and repeat the process: 4773 / 647

Going ahead to step 7:
When dividing 4773 by 647, we get 7 with a remainder of 244.
Use 7 as the next digit of our solution. 
Result so far: 10917.0
Subtracting 4529 from 4773 leaves us with 244.
Append the next digit (9) from the dividend to 244 and continue with: 2449 / 647

Going ahead to step 8:
When dividing 2449 by 647, we get 3 with a remainder of 508.
Put 3 as the next digit of the answer. 
Result so far: 109173.0
Subtracting 1941 from 2449 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 9:
647 goes into 5080 7 times with a remainder of 551.
Use 7 as the next digit of our solution. 
Result so far: 109173.7
If we subtract 4529 from 5080, we get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 10:
When dividing 5510 by 647, we get 8 with a remainder of 334.
Record the quotient 8 as the next digit in the result. 
Result so far: 109173.78
If we take 5176 away from 5510, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 11:
If we divide 3340 by 647, we get 5 and a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 109173.785
Subtracting 3235 from 3340 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 12:
The number 647 fits into 1050 1 times, leaving a remainder of 403.
The number 1 becomes the next digit in our result. 
Result so far: 109173.7851
Deduct 647 from 1050 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Advancing to step 13:
If we divide 4030 by 647, we get 6 and a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 109173.78516
Subtracting 3882 from 4030 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 14:
The number 647 fits into 1480 2 times, leaving a remainder of 186.
The next digit of our result is 2. 
Result so far: 109173.785162
Subtracting 1294 from 1480 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 15:
If we divide 1860 by 647, we get 2 and a remainder of 566.
Put 2 as the next digit of the answer. 
Result so far: 109173.7851622
Subtracting 1294 from 1860 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Our division results in 109173.7851622 with a remaining 5.66e-06.
