86361076 ÷ 251 
We want to divide 86361076 by 251.

Let's proceed to step 1:
The number 251 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 251

Step 2:
When dividing 86 by 251, we get 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 251

Going ahead to step 3:
863 divided by 251 is 3 with a remainder of 110.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 753 from 863, we get 110.
Include the next digit (6) from the dividend after 110, then repeat: 1106 / 251

Going ahead to step 4:
If we divide 1106 by 251, we get 4 and a remainder of 102.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 1004 from 1106 and we're left with 102.
Bring next digit (1) of the dividend behind the 102 and repeat the process: 1021 / 251

Moving on to step 5:
251 can be fit into 1021 4 times, resulting in a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 344.0
If we take 1004 away from 1021, we end up with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 251

Let's proceed to step 6:
251 can be fit into 170 0 times, resulting in a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 3440.0
Subtracting 0 from 170 leaves us with 170.
Append the next digit (7) from the dividend to 170 and continue with: 1707 / 251

Advancing to step 7:
The number 251 fits into 1707 6 times, leaving a remainder of 201.
The number 6 becomes the next digit in our result. 
Result so far: 34406.0
If we subtract 1506 from 1707, we get 201.
Grab the next digit (6) from the dividend, add it to 201, then carry on: 2016 / 251

Step 8:
If we divide 2016 by 251, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 344068.0
Subtracting 2008 from 2016 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
251 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 344068.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
If we divide 800 by 251, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 344068.03
Deduct 753 from 800 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
When dividing 470 by 251, we get 1 with a remainder of 219.
The next digit of our result is 1. 
Result so far: 344068.031
Subtract 251 from 470 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 12:
When dividing 2190 by 251, we get 8 with a remainder of 182.
Use 8 as the next digit of our solution. 
Result so far: 344068.0318
If we take 2008 away from 2190, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 13:
The number 251 fits into 1820 7 times, leaving a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 344068.03187
Deduct 1757 from 1820 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
251 goes into 630 2 times with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 344068.031872
Subtract 502 from 630 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 15:
The number 251 fits into 1280 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 344068.0318725
Subtracting 1255 from 1280 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.

Advancing to step 16:
When dividing 250 by 251, we get 0 with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 344068.0318725
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 344068.0318725 with a remainder of 2.5e-07.
