We're dividing 400957 by 86 
Our goal is to divide 400957 by 86.

Moving on to step 1:
86 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 86

Advancing to step 2:
When dividing 40 by 86, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 86

Moving on to step 3:
If we divide 400 by 86, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 344 away from 400, we end up with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 86

Step 4:
When dividing 569 by 86, we get 6 with a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 516 away from 569, we end up with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 86

Advancing to step 5:
86 goes into 535 6 times with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 466.0
If we take 516 away from 535, we end up with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 86

Going ahead to step 6:
If we divide 197 by 86, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 4662.0
Subtracting 172 from 197 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
When dividing 250 by 86, we get 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 4662.2
Subtracting 172 from 250 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 8:
86 can be fit into 780 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 4662.29
Subtract 774 from 780 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 86, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4662.29
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 86, we get 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 4662.2906
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 4662.29069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
When dividing 660 by 86, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 4662.290697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
86 goes into 580 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 4662.2906976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
If we divide 640 by 86, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 4662.29069767
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 4662.29069767 with a balance of 3.8e-08.
