87121425 ÷ 432 
Let's see how many times 432 fits into 87121425.

Moving on to step 1:
8 divided by 432 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 432

Let's proceed to step 2:
The number 432 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (1) from the dividend to 87 and continue with: 871 / 432

On to step 3:
The number 432 fits into 871 2 times, leaving a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 7 after subtracting 864 from 871.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 432

Let's proceed to step 4:
72 divided by 432 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 432

Step 5:
721 divided by 432 is 1 with a remainder of 289.
Write down 1 as next digit of the result. 
Result so far: 201.0
Subtract 432 from 721 to get 289.
Take the next digit (4) from the dividend and append it to 289, then repeat: 2894 / 432

Going ahead to step 6:
The number 432 fits into 2894 6 times, leaving a remainder of 302.
The number 6 becomes the next digit in our result. 
Result so far: 2016.0
The remainder is 302 after subtracting 2592 from 2894.
Take the next digit (2) from the dividend and append it to 302, then repeat: 3022 / 432

Going ahead to step 7:
432 goes into 3022 6 times with a remainder of 430.
Put 6 as the next digit of the answer. 
Result so far: 20166.0
Deduct 2592 from 3022 and we're left with 430.
Fetch the next digit (5) from the dividend, attach it to 430 and continue: 4305 / 432

Moving on to step 8:
432 goes into 4305 9 times with a remainder of 417.
The number 9 becomes the next digit in our result. 
Result so far: 201669.0
If we subtract 3888 from 4305, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Let's proceed to step 9:
If we divide 4170 by 432, we get 9 and a remainder of 282.
Put 9 as the next digit of the answer. 
Result so far: 201669.9
Subtract 3888 from 4170 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 10:
The number 432 fits into 2820 6 times, leaving a remainder of 228.
Record the quotient 6 as the next digit in the result. 
Result so far: 201669.96
If we take 2592 away from 2820, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
The number 432 fits into 2280 5 times, leaving a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 201669.965
The remainder is 120 after subtracting 2160 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
The number 432 fits into 1200 2 times, leaving a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 201669.9652
Subtract 864 from 1200 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 13:
The number 432 fits into 3360 7 times, leaving a remainder of 336.
Put 7 as the next digit of the answer. 
Result so far: 201669.96527
The remainder is 336 after subtracting 3024 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 14:
When dividing 3360 by 432, we get 7 with a remainder of 336.
The next digit of our result is 7. 
Result so far: 201669.965277
Subtracting 3024 from 3360 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

After the division, we end up with 201669.965277 and a remainder of 3.36e-05.
