We look at the division of 90616031 by 431 
We want to figure out the number of times 90616031 can be divided by 431.

Let's proceed to step 1:
431 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 431

Advancing to step 2:
90 divided by 431 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (6) from the dividend to 90 and continue with: 906 / 431

Going ahead to step 3:
The number 431 fits into 906 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 44 after subtracting 862 from 906.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 431

On to step 4:
441 divided by 431 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 431 from 441 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 431

Advancing to step 5:
106 divided by 431 is 0 with a remainder of 106.
The next digit of our result is 0. 
Result so far: 210.0
Subtract 0 from 106 to get 106.
Append the next digit (0) from the dividend to 106 and continue with: 1060 / 431

Moving on to step 6:
1060 divided by 431 is 2 with a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 2102.0
Deduct 862 from 1060 and we're left with 198.
Bring next digit (3) of the dividend behind the 198 and repeat the process: 1983 / 431

Advancing to step 7:
If we divide 1983 by 431, we get 4 and a remainder of 259.
Put 4 as the next digit of the answer. 
Result so far: 21024.0
If we subtract 1724 from 1983, we get 259.
Fetch the next digit (1) from the dividend, attach it to 259 and continue: 2591 / 431

Let's proceed to step 8:
When dividing 2591 by 431, we get 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 210246.0
Subtract 2586 from 2591 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
431 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 210246.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 431, we get 1 and a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 210246.01
Deduct 431 from 500 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 11:
The number 431 fits into 690 1 times, leaving a remainder of 259.
The number 1 becomes the next digit in our result. 
Result so far: 210246.011
The remainder is 259 after subtracting 431 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

After the division, we end up with 210246.011 and a remainder of 0.0259.
