We're dividing 67415842 by 431 
We want to divide 67415842 by 431.

Going ahead to step 1:
431 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 431

On to step 2:
If we divide 67 by 431, we get 0 and a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 431

Step 3:
674 divided by 431 is 1 with a remainder of 243.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 431 from 674, we get 243.
Take the next digit (1) from the dividend and append it to 243, then repeat: 2431 / 431

Step 4:
The number 431 fits into 2431 5 times, leaving a remainder of 276.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2155 away from 2431, we end up with 276.
Fetch the next digit (5) from the dividend, attach it to 276 and continue: 2765 / 431

Step 5:
If we divide 2765 by 431, we get 6 and a remainder of 179.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Deduct 2586 from 2765 and we're left with 179.
Take the next digit (8) from the dividend and append it to 179, then repeat: 1798 / 431

On to step 6:
431 can be fit into 1798 4 times, resulting in a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 1564.0
The remainder is 74 after subtracting 1724 from 1798.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 431

Advancing to step 7:
If we divide 744 by 431, we get 1 and a remainder of 313.
The number 1 becomes the next digit in our result. 
Result so far: 15641.0
Subtracting 431 from 744 leaves us with 313.
Bring next digit (2) of the dividend behind the 313 and repeat the process: 3132 / 431

Moving on to step 8:
If we divide 3132 by 431, we get 7 and a remainder of 115.
The next digit of our result is 7. 
Result so far: 156417.0
Deduct 3017 from 3132 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 9:
If we divide 1150 by 431, we get 2 and a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 156417.2
If we take 862 away from 1150, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 10:
When dividing 2880 by 431, we get 6 with a remainder of 294.
Put 6 as the next digit of the answer. 
Result so far: 156417.26
If we subtract 2586 from 2880, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 11:
2940 divided by 431 is 6 with a remainder of 354.
Record the quotient 6 as the next digit in the result. 
Result so far: 156417.266
If we take 2586 away from 2940, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The final outcome is 156417.266, with a leftover of 0.0354.
