Let's divide 642431 by 70
We're looking to find how many times 70 goes into 642431.

Step 1:
The number 70 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 70

Going ahead to step 2:
70 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 70

Advancing to step 3:
70 can be fit into 642 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 630 from 642 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 70

On to step 4:
The number 70 fits into 124 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we take 70 away from 124, we end up with 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 70

On to step 5:
If we divide 543 by 70, we get 7 and a remainder of 53.
The next digit of our result is 7. 
Result so far: 917.0
If we subtract 490 from 543, we get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 70

Moving on to step 6:
If we divide 531 by 70, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 9177.0
Subtracting 490 from 531 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
70 goes into 410 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 9177.5
Subtract 350 from 410 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.

Let's proceed to step 8:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 9177.58
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.

Let's proceed to step 9:
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: 9177.585
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.

Let's proceed to step 10:
When dividing 500 by 70, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 9177.5857
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.

On to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 9177.58571
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 12:
When dividing 300 by 70, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 9177.585714
If we subtract 280 from 300, we 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.

Let's proceed to step 13:
When dividing 200 by 70, we get 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 9177.5857142
If we subtract 140 from 200, we 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.

Let's proceed to step 14:
If we divide 600 by 70, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 9177.58571428
Subtract 560 from 600 to 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.

After the division, we end up with 9177.58571428 and a remainder of 4e-08.
