We look at the division of 42831507 by 786 
Let's see how many times 786 fits into 42831507.

On to step 1:
4 divided by 786 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 786

Going ahead to step 2:
786 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 786

Step 3:
786 can be fit into 428 0 times, resulting in a remainder of 428.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 428 leaves us with 428.
Append the next digit (3) from the dividend to 428 and continue with: 4283 / 786

Step 4:
If we divide 4283 by 786, we get 5 and a remainder of 353.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 3930 away from 4283, we end up with 353.
Take the next digit (1) from the dividend and append it to 353, then repeat: 3531 / 786

Step 5:
When dividing 3531 by 786, we get 4 with a remainder of 387.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 387 after subtracting 3144 from 3531.
Include the next digit (5) from the dividend after 387, then repeat: 3875 / 786

Step 6:
The number 786 fits into 3875 4 times, leaving a remainder of 731.
Use 4 as the next digit of our solution. 
Result so far: 544.0
The remainder is 731 after subtracting 3144 from 3875.
Fetch the next digit (0) from the dividend, attach it to 731 and continue: 7310 / 786

Step 7:
If we divide 7310 by 786, we get 9 and a remainder of 236.
Put 9 as the next digit of the answer. 
Result so far: 5449.0
If we take 7074 away from 7310, we end up with 236.
Fetch the next digit (7) from the dividend, attach it to 236 and continue: 2367 / 786

Going ahead to step 8:
2367 divided by 786 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 54493.0
If we take 2358 away from 2367, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 786 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 54493.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
786 can be fit into 900 1 times, resulting in a remainder of 114.
The next digit of our result is 1. 
Result so far: 54493.01
Subtract 786 from 900 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
The number 786 fits into 1140 1 times, leaving a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 54493.011
If we subtract 786 from 1140, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 54493.011 with a remaining 0.0354.
