Let's divide 643955 by 70
Let's see how many times 70 fits into 643955.

Going ahead to step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 70

Let's proceed to step 2:
70 goes into 64 0 times 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.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 70

Going ahead to step 3:
643 divided by 70 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 630 from 643 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 70

Advancing to step 4:
70 goes into 139 1 times with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 70 from 139 to get 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 70

Advancing to step 5:
If we divide 695 by 70, we get 9 and a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 919.0
Deduct 630 from 695 and we're left with 65.
Append the next digit (5) from the dividend to 65 and continue with: 655 / 70

Moving on to step 6:
When dividing 655 by 70, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 9199.0
Subtract 630 from 655 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
70 goes into 250 3 times with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 9199.3
The remainder is 40 after subtracting 210 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 9199.35
If we take 350 away from 400, we end up with 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 9:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 9199.357
Subtract 490 from 500 to 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 10:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 9199.3571
Subtract 70 from 100 to 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.

Let's proceed to step 11:
300 divided by 70 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9199.35714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 9199.357142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9199.3571428
If we subtract 560 from 600, we get 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 14:
If we divide 400 by 70, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9199.35714285
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 9199.35714285 with a balance of 5e-08.
