80852121 divided by 259 
We're looking to find how many times 259 goes into 80852121.

Let's proceed to step 1:
259 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 259

Advancing to step 2:
259 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 259

Advancing to step 3:
The number 259 fits into 808 3 times, leaving a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 777 away from 808, we end up with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 259

Step 4:
259 goes into 315 1 times with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 259 from 315 and we're left with 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 259

Advancing to step 5:
562 divided by 259 is 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 312.0
If we subtract 518 from 562, we get 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 259

Going ahead to step 6:
259 goes into 441 1 times with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 3121.0
Deduct 259 from 441 and we're left with 182.
Fetch the next digit (2) from the dividend, attach it to 182 and continue: 1822 / 259

Going ahead to step 7:
1822 divided by 259 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 31217.0
The remainder is 9 after subtracting 1813 from 1822.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 259

Let's proceed to step 8:
When dividing 91 by 259, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 312170.0
Subtracting 0 from 91 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 9:
When dividing 910 by 259, we get 3 with a remainder of 133.
Write down 3 as next digit of the result. 
Result so far: 312170.3
The remainder is 133 after subtracting 777 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 10:
259 goes into 1330 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 312170.35
The remainder is 35 after subtracting 1295 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
When dividing 350 by 259, we get 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 312170.351
If we take 259 away from 350, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 12:
If we divide 910 by 259, we get 3 and a remainder of 133.
Use 3 as the next digit of our solution. 
Result so far: 312170.3513
Subtracting 777 from 910 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 13:
The number 259 fits into 1330 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 312170.35135
Subtract 1295 from 1330 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
When dividing 350 by 259, we get 1 with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 312170.351351
Subtracting 259 from 350 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 15:
259 can be fit into 910 3 times, resulting in a remainder of 133.
The number 3 becomes the next digit in our result. 
Result so far: 312170.3513513
The remainder is 133 after subtracting 777 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 16:
If we divide 1330 by 259, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 312170.35135135
Deduct 1295 from 1330 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 312170.35135135 with a balance of 3.5e-08.
