90609263 ÷ 428 
We want to figure out the number of times 90609263 can be divided by 428.

Step 1:
The number 428 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 428

On to step 2:
The number 428 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Grab the next digit (6) from the dividend, add it to 90, then carry on: 906 / 428

Going ahead to step 3:
428 can be fit into 906 2 times, resulting in a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 856 from 906 and we're left with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 428

On to step 4:
428 goes into 500 1 times with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 428 from 500 and we're left with 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 428

On to step 5:
729 divided by 428 is 1 with a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 211.0
Deduct 428 from 729 and we're left with 301.
Bring next digit (2) of the dividend behind the 301 and repeat the process: 3012 / 428

Moving on to step 6:
When dividing 3012 by 428, we get 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 2117.0
Subtract 2996 from 3012 to get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 428

Step 7:
If we divide 166 by 428, we get 0 and a remainder of 166.
Write down 0 as next digit of the result. 
Result so far: 21170.0
If we take 0 away from 166, we end up with 166.
Append the next digit (3) from the dividend to 166 and continue with: 1663 / 428

Let's proceed to step 8:
428 can be fit into 1663 3 times, resulting in a remainder of 379.
Use 3 as the next digit of our solution. 
Result so far: 211703.0
Deduct 1284 from 1663 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 9:
The number 428 fits into 3790 8 times, leaving a remainder of 366.
Use 8 as the next digit of our solution. 
Result so far: 211703.8
Deduct 3424 from 3790 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 10:
When dividing 3660 by 428, we get 8 with a remainder of 236.
Record the quotient 8 as the next digit in the result. 
Result so far: 211703.88
Subtract 3424 from 3660 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

In conclusion, the division gives 211703.88 with a balance of 0.236.
