90123152 ÷ 430 
Our goal is to divide 90123152 by 430.

Let's proceed to step 1:
If we divide 9 by 430, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 430

Advancing to step 2:
90 divided by 430 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 430

Step 3:
If we divide 901 by 430, we get 2 and a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 860 away from 901, we end up with 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 430

Advancing to step 4:
When dividing 412 by 430, we get 0 with a remainder of 412.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 412 after subtracting 0 from 412.
Fetch the next digit (3) from the dividend, attach it to 412 and continue: 4123 / 430

Going ahead to step 5:
430 goes into 4123 9 times with a remainder of 253.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Deduct 3870 from 4123 and we're left with 253.
Fetch the next digit (1) from the dividend, attach it to 253 and continue: 2531 / 430

Let's proceed to step 6:
If we divide 2531 by 430, we get 5 and a remainder of 381.
Use 5 as the next digit of our solution. 
Result so far: 2095.0
Deduct 2150 from 2531 and we're left with 381.
Bring next digit (5) of the dividend behind the 381 and repeat the process: 3815 / 430

Let's proceed to step 7:
When dividing 3815 by 430, we get 8 with a remainder of 375.
Put 8 as the next digit of the answer. 
Result so far: 20958.0
Subtracting 3440 from 3815 leaves us with 375.
Append the next digit (2) from the dividend to 375 and continue with: 3752 / 430

Advancing to step 8:
The number 430 fits into 3752 8 times, leaving a remainder of 312.
Put 8 as the next digit of the answer. 
Result so far: 209588.0
Subtracting 3440 from 3752 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 9:
The number 430 fits into 3120 7 times, leaving a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 209588.7
Subtracting 3010 from 3120 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
430 can be fit into 1100 2 times, resulting in a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 209588.72
The remainder is 240 after subtracting 860 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
430 can be fit into 2400 5 times, resulting in a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 209588.725
Deduct 2150 from 2400 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
The number 430 fits into 2500 5 times, leaving a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 209588.7255
Subtract 2150 from 2500 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The quotient of the division is 209588.7255, and the remainder is 0.0035.
