We're dividing 86555379 by 401 
We want to figure out the number of times 86555379 can be divided by 401.

Going ahead to step 1:
8 divided by 401 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 401

Moving on to step 2:
401 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 401

Step 3:
865 divided by 401 is 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 802 from 865 to get 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 401

Going ahead to step 4:
635 divided by 401 is 1 with a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 401 from 635 and we're left with 234.
Bring next digit (5) of the dividend behind the 234 and repeat the process: 2345 / 401

Moving on to step 5:
401 can be fit into 2345 5 times, resulting in a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Subtracting 2005 from 2345 leaves us with 340.
Fetch the next digit (3) from the dividend, attach it to 340 and continue: 3403 / 401

Let's proceed to step 6:
When dividing 3403 by 401, we get 8 with a remainder of 195.
The number 8 becomes the next digit in our result. 
Result so far: 2158.0
Deduct 3208 from 3403 and we're left with 195.
Grab the next digit (7) from the dividend, add it to 195, then carry on: 1957 / 401

Step 7:
401 goes into 1957 4 times with a remainder of 353.
Put 4 as the next digit of the answer. 
Result so far: 21584.0
If we subtract 1604 from 1957, we get 353.
Grab the next digit (9) from the dividend, add it to 353, then carry on: 3539 / 401

Moving on to step 8:
When dividing 3539 by 401, we get 8 with a remainder of 331.
Use 8 as the next digit of our solution. 
Result so far: 215848.0
If we take 3208 away from 3539, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 9:
If we divide 3310 by 401, we get 8 and a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 215848.8
Deduct 3208 from 3310 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 10:
When dividing 1020 by 401, we get 2 with a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 215848.82
The remainder is 218 after subtracting 802 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 11:
When dividing 2180 by 401, we get 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 215848.825
The remainder is 175 after subtracting 2005 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
The number 401 fits into 1750 4 times, leaving a remainder of 146.
Use 4 as the next digit of our solution. 
Result so far: 215848.8254
Subtracting 1604 from 1750 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 13:
When dividing 1460 by 401, we get 3 with a remainder of 257.
The next digit of our result is 3. 
Result so far: 215848.82543
Subtract 1203 from 1460 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 14:
401 goes into 2570 6 times with a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 215848.825436
Subtracting 2406 from 2570 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 15:
401 goes into 1640 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 215848.8254364
If we subtract 1604 from 1640, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
If we divide 360 by 401, we get 0 and a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 215848.8254364
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 215848.8254364, and the remainder is 3.6e-07.
