90429657 divided by 215 
We want to divide 90429657 by 215.

Advancing to step 1:
When dividing 9 by 215, we get 0 with 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 / 215

Moving on to step 2:
90 divided by 215 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 215

Moving on to step 3:
215 can be fit into 904 4 times, resulting in a remainder of 44.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 860 from 904 leaves us with 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 215

Advancing to step 4:
215 can be fit into 442 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 12 after subtracting 430 from 442.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 215

Going ahead to step 5:
215 goes into 129 0 times with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 420.0
Subtract 0 from 129 to get 129.
Append the next digit (6) from the dividend to 129 and continue with: 1296 / 215

Advancing to step 6:
1296 divided by 215 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 4206.0
Subtract 1290 from 1296 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 215

Moving on to step 7:
If we divide 65 by 215, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 42060.0
The remainder is 65 after subtracting 0 from 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 215

Let's proceed to step 8:
If we divide 657 by 215, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 420603.0
The remainder is 12 after subtracting 645 from 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
When dividing 120 by 215, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 420603.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
215 goes into 1200 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 420603.05
Subtract 1075 from 1200 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 11:
1250 divided by 215 is 5 with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 420603.055
Subtracting 1075 from 1250 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

In conclusion, the division gives 420603.055 with a balance of 0.0175.
