Let's divide 90458 by 70
We want to figure out the number of times 90458 can be divided by 70.

On to step 1:
70 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 70

Let's proceed to step 2:
When dividing 90 by 70, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 20 after subtracting 70 from 90.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 70

Step 3:
The number 70 fits into 204 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 12.0
If we take 140 away from 204, we end up with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 70

Moving on to step 4:
70 goes into 645 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 129.0
Subtracting 630 from 645 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 70

On to step 5:
158 divided by 70 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1292.0
If we take 140 away from 158, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 6:
70 can be fit into 180 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 1292.2
If we subtract 140 from 180, 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.

Moving on to step 7:
If we divide 400 by 70, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 1292.25
If we subtract 350 from 400, 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.

Step 8:
When dividing 500 by 70, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 1292.257
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.

On to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1292.2571
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.
Write down 4 as next digit of the result. 
Result so far: 1292.25714
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.

Let's proceed to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 1292.257142
Subtracting 140 from 200 leaves us 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.

Going ahead to step 12:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 1292.2571428
The remainder is 40 after subtracting 560 from 600.
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 13:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1292.25714285
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.

The final outcome is 1292.25714285, with a leftover of 5e-08.
