We look at the division of 645436 by 70 
Let's see how many times 70 fits into 645436.

Step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 70

Moving on to step 2:
64 divided by 70 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 70

Let's proceed to step 3:
If we divide 645 by 70, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 630 away from 645, we end up with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 70

Going ahead to step 4:
70 goes into 154 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 92.0
The remainder is 14 after subtracting 140 from 154.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 70

Moving on to step 5:
70 can be fit into 143 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 922.0
Subtract 140 from 143 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 70

Going ahead to step 6:
70 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 9220.0
Subtract 0 from 36 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
70 goes into 360 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9220.5
The remainder is 10 after subtracting 350 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
70 goes into 100 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 9220.51
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.

Let's proceed to step 9:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 9220.514
Subtracting 280 from 300 leaves us 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.

Going ahead to step 10:
When dividing 200 by 70, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 9220.5142
If we take 140 away from 200, we end up 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 11:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 9220.51428
Subtracting 560 from 600 leaves us 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.

Going ahead to step 12:
When dividing 400 by 70, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9220.514285
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.

Step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9220.5142857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
70 goes into 100 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 9220.51428571
If we take 70 away from 100, 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.

The final outcome is 9220.51428571, with a leftover of 3e-08.
