643298 ÷ 70 
Let's see how many times 70 fits into 643298.

Moving on to step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
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 / 70

Advancing to step 2:
When dividing 64 by 70, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 70

Step 3:
If we divide 643 by 70, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 630 from 643 leaves us with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 70

Let's proceed to step 4:
70 goes into 132 1 times with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 70 from 132 to get 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 70

Moving on to step 5:
70 can be fit into 629 8 times, resulting in a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 918.0
Deduct 560 from 629 and we're left with 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 70

Advancing to step 6:
698 divided by 70 is 9 with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 9189.0
If we take 630 away from 698, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
When dividing 680 by 70, we get 9 with a remainder of 50.
The next digit of our result is 9. 
Result so far: 9189.9
If we subtract 630 from 680, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 9189.97
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 70, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 9189.971
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 9189.9714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 9189.97142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
600 divided by 70 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 9189.971428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9189.9714285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 9189.97142857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 9189.97142857 and a remainder of 1e-08.
