90209326 ÷ 140 
We want to figure out the number of times 90209326 can be divided by 140.

Going ahead to step 1:
140 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 140

Step 2:
140 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 140

Moving on to step 3:
If we divide 902 by 140, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 840 from 902 leaves us with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 140

On to step 4:
If we divide 620 by 140, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 560 from 620 leaves us with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 140

Moving on to step 5:
If we divide 609 by 140, we get 4 and a remainder of 49.
The next digit of our result is 4. 
Result so far: 644.0
Subtract 560 from 609 to get 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 140

Let's proceed to step 6:
493 divided by 140 is 3 with a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 6443.0
Subtract 420 from 493 to get 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 140

On to step 7:
140 goes into 732 5 times with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 64435.0
Deduct 700 from 732 and we're left with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 140

Moving on to step 8:
326 divided by 140 is 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 644352.0
If we subtract 280 from 326, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
460 divided by 140 is 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 644352.3
Subtracting 420 from 460 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.

On to step 10:
400 divided by 140 is 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 644352.32
If we take 280 away from 400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
If we divide 1200 by 140, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 644352.328
Deduct 1120 from 1200 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
140 can be fit into 800 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 644352.3285
Deduct 700 from 800 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
If we divide 1000 by 140, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 644352.32857
If we subtract 980 from 1000, 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.

On to step 14:
140 can be fit into 200 1 times, resulting in a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 644352.328571
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 15:
The number 140 fits into 600 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 644352.3285714
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 16:
140 can be fit into 400 2 times, resulting in a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 644352.32857142
The remainder is 120 after subtracting 280 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 644352.32857142 and a remainder of 1.2e-07.
