We're dividing 87143933 by 431 
We're looking to find how many times 431 goes into 87143933.

Advancing to step 1:
When dividing 8 by 431, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 431

Going ahead to step 2:
431 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 431

Step 3:
431 can be fit into 871 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 862 from 871 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 431

Moving on to step 4:
431 can be fit into 94 0 times, resulting in a remainder of 94.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 94, we get 94.
Take the next digit (3) from the dividend and append it to 94, then repeat: 943 / 431

Moving on to step 5:
The number 431 fits into 943 2 times, leaving a remainder of 81.
The next digit of our result is 2. 
Result so far: 202.0
Subtract 862 from 943 to get 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 431

Let's proceed to step 6:
819 divided by 431 is 1 with a remainder of 388.
The number 1 becomes the next digit in our result. 
Result so far: 2021.0
If we subtract 431 from 819, we get 388.
Grab the next digit (3) from the dividend, add it to 388, then carry on: 3883 / 431

Moving on to step 7:
When dividing 3883 by 431, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 20219.0
Deduct 3879 from 3883 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 431

Advancing to step 8:
43 divided by 431 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 202190.0
If we subtract 0 from 43, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
When dividing 430 by 431, we get 0 with a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 202190.0
Subtract 0 from 430 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 10:
431 can be fit into 4300 9 times, resulting in a remainder of 421.
Record the quotient 9 as the next digit in the result. 
Result so far: 202190.09
If we subtract 3879 from 4300, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 11:
431 can be fit into 4210 9 times, resulting in a remainder of 331.
The number 9 becomes the next digit in our result. 
Result so far: 202190.099
If we subtract 3879 from 4210, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The quotient of the division is 202190.099, and the remainder is 0.0331.
