We look at the division of 405125 by 986 
Let's see how many times 986 fits into 405125.

Let's proceed to step 1:
When dividing 4 by 986, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 986

Advancing to step 2:
If we divide 40 by 986, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 986

Going ahead to step 3:
986 goes into 405 0 times with a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 405, we end up with 405.
Append the next digit (1) from the dividend to 405 and continue with: 4051 / 986

Advancing to step 4:
986 can be fit into 4051 4 times, resulting in a remainder of 107.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3944 from 4051 and we're left with 107.
Append the next digit (2) from the dividend to 107 and continue with: 1072 / 986

Moving on to step 5:
If we divide 1072 by 986, we get 1 and a remainder of 86.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtracting 986 from 1072 leaves us with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 986

Let's proceed to step 6:
986 goes into 865 0 times with a remainder of 865.
The number 0 becomes the next digit in our result. 
Result so far: 410.0
If we take 0 away from 865, we end up with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

On to step 7:
If we divide 8650 by 986, we get 8 and a remainder of 762.
Write down 8 as next digit of the result. 
Result so far: 410.8
If we take 7888 away from 8650, we end up with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 8:
986 goes into 7620 7 times with a remainder of 718.
Use 7 as the next digit of our solution. 
Result so far: 410.87
If we take 6902 away from 7620, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Going ahead to step 9:
986 goes into 7180 7 times with a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 410.877
Deduct 6902 from 7180 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

In conclusion, the division gives 410.877 with a balance of 0.0278.
