We look at the division of 400948 by 86 
We want to divide 400948 by 86.

Moving on to step 1:
4 divided by 86 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 86

Step 2:
86 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 86

Step 3:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 344 from 400 to get 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 86

Let's proceed to step 4:
86 can be fit into 569 6 times, resulting in a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 53 after subtracting 516 from 569.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 86

Let's proceed to step 5:
The number 86 fits into 534 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 466.0
Subtracting 516 from 534 leaves us with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 86

Step 6:
86 can be fit into 188 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 4662.0
If we take 172 away from 188, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 86 fits into 160 1 times, leaving a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 4662.1
The remainder is 74 after subtracting 86 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 4662.18
Deduct 688 from 740 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
When dividing 520 by 86, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4662.186
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
86 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4662.186
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 4662.18604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
86 goes into 560 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 4662.186046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
If we divide 440 by 86, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4662.1860465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 86 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 4662.18604651
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 4662.18604651 with a remaining 1.4e-08.
