90422277 ÷ 231 
We want to figure out the number of times 90422277 can be divided by 231.

Step 1:
When dividing 9 by 231, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 231

Advancing to step 2:
231 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 231

On to step 3:
If we divide 904 by 231, we get 3 and a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 693 away from 904, we end up with 211.
Grab the next digit (2) from the dividend, add it to 211, then carry on: 2112 / 231

Going ahead to step 4:
2112 divided by 231 is 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 33 after subtracting 2079 from 2112.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 231

Step 5:
The number 231 fits into 332 1 times, leaving a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 391.0
If we take 231 away from 332, we end up with 101.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 231

Advancing to step 6:
231 can be fit into 1012 4 times, resulting in a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 3914.0
Deduct 924 from 1012 and we're left with 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 231

On to step 7:
231 goes into 887 3 times with a remainder of 194.
The next digit of our result is 3. 
Result so far: 39143.0
Deduct 693 from 887 and we're left with 194.
Include the next digit (7) from the dividend after 194, then repeat: 1947 / 231

Step 8:
231 can be fit into 1947 8 times, resulting in a remainder of 99.
The next digit of our result is 8. 
Result so far: 391438.0
Deduct 1848 from 1947 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 9:
When dividing 990 by 231, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 391438.4
Subtract 924 from 990 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
The number 231 fits into 660 2 times, leaving a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 391438.42
The remainder is 198 after subtracting 462 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 11:
The number 231 fits into 1980 8 times, leaving a remainder of 132.
The next digit of our result is 8. 
Result so far: 391438.428
The remainder is 132 after subtracting 1848 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 12:
231 goes into 1320 5 times with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 391438.4285
Subtract 1155 from 1320 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 13:
231 can be fit into 1650 7 times, resulting in a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 391438.42857
If we take 1617 away from 1650, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
330 divided by 231 is 1 with a remainder of 99.
The next digit of our result is 1. 
Result so far: 391438.428571
Subtract 231 from 330 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 15:
The number 231 fits into 990 4 times, leaving a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 391438.4285714
The remainder is 66 after subtracting 924 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 16:
231 can be fit into 660 2 times, resulting in a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 391438.42857142
If we subtract 462 from 660, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

After the division, we end up with 391438.42857142 and a remainder of 1.98e-07.
