We're dividing 7620991 by 431 
We're looking to find how many times 431 goes into 7620991.

Step 1:
7 divided by 431 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 431

On to step 2:
When dividing 76 by 431, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 431

Moving on to step 3:
431 goes into 762 1 times with a remainder of 331.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 431 from 762 leaves us with 331.
Take the next digit (0) from the dividend and append it to 331, then repeat: 3310 / 431

Step 4:
If we divide 3310 by 431, we get 7 and a remainder of 293.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 293 after subtracting 3017 from 3310.
Take the next digit (9) from the dividend and append it to 293, then repeat: 2939 / 431

Let's proceed to step 5:
The number 431 fits into 2939 6 times, leaving a remainder of 353.
Write down 6 as next digit of the result. 
Result so far: 176.0
Subtract 2586 from 2939 to get 353.
Bring next digit (9) of the dividend behind the 353 and repeat the process: 3539 / 431

Let's proceed to step 6:
3539 divided by 431 is 8 with a remainder of 91.
Use 8 as the next digit of our solution. 
Result so far: 1768.0
Deduct 3448 from 3539 and we're left with 91.
Fetch the next digit (1) from the dividend, attach it to 91 and continue: 911 / 431

Going ahead to step 7:
The number 431 fits into 911 2 times, leaving a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 17682.0
Subtracting 862 from 911 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 8:
490 divided by 431 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 17682.1
Subtract 431 from 490 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
431 can be fit into 590 1 times, resulting in a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 17682.11
Subtract 431 from 590 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

In conclusion, the division gives 17682.11 with a balance of 0.159.
