We look at the division of 86425366 by 261 
We're looking to find how many times 261 goes into 86425366.

On to step 1:
The number 261 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 261

Step 2:
261 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 261

Advancing to step 3:
261 can be fit into 864 3 times, resulting in a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 783 away from 864, we end up with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 261

Moving on to step 4:
The number 261 fits into 812 3 times, leaving a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 783 from 812 to get 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 261

Going ahead to step 5:
If we divide 295 by 261, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 331.0
If we take 261 away from 295, we end up with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 261

Advancing to step 6:
343 divided by 261 is 1 with a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 3311.0
If we take 261 away from 343, we end up with 82.
Bring next digit (6) of the dividend behind the 82 and repeat the process: 826 / 261

On to step 7:
When dividing 826 by 261, we get 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 33113.0
Deduct 783 from 826 and we're left with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 261

Moving on to step 8:
When dividing 436 by 261, we get 1 with a remainder of 175.
The number 1 becomes the next digit in our result. 
Result so far: 331131.0
Subtract 261 from 436 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 9:
261 goes into 1750 6 times with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 331131.6
If we subtract 1566 from 1750, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 10:
261 goes into 1840 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 331131.67
Subtracting 1827 from 1840 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
130 divided by 261 is 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 331131.67
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
261 can be fit into 1300 4 times, resulting in a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 331131.6704
Subtract 1044 from 1300 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 13:
If we divide 2560 by 261, we get 9 and a remainder of 211.
Write down 9 as next digit of the result. 
Result so far: 331131.67049
Subtracting 2349 from 2560 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 14:
The number 261 fits into 2110 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 331131.670498
If we take 2088 away from 2110, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
If we divide 220 by 261, we get 0 and a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 331131.670498
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 16:
2200 divided by 261 is 8 with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 331131.67049808
Subtracting 2088 from 2200 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 331131.67049808, with a leftover of 1.12e-07.
