We're dividing 89316274 by 259 
Our goal is to divide 89316274 by 259.

On to step 1:
When dividing 8 by 259, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 259

Going ahead to step 2:
259 goes into 89 0 times with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Grab the next digit (3) from the dividend, add it to 89, then carry on: 893 / 259

Going ahead to step 3:
893 divided by 259 is 3 with a remainder of 116.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 777 from 893 leaves us with 116.
Append the next digit (1) from the dividend to 116 and continue with: 1161 / 259

Advancing to step 4:
If we divide 1161 by 259, we get 4 and a remainder of 125.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 1036 from 1161 to get 125.
Grab the next digit (6) from the dividend, add it to 125, then carry on: 1256 / 259

On to step 5:
If we divide 1256 by 259, we get 4 and a remainder of 220.
The next digit of our result is 4. 
Result so far: 344.0
If we subtract 1036 from 1256, we get 220.
Append the next digit (2) from the dividend to 220 and continue with: 2202 / 259

Moving on to step 6:
If we divide 2202 by 259, we get 8 and a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 3448.0
Deduct 2072 from 2202 and we're left with 130.
Grab the next digit (7) from the dividend, add it to 130, then carry on: 1307 / 259

Advancing to step 7:
The number 259 fits into 1307 5 times, leaving a remainder of 12.
The next digit of our result is 5. 
Result so far: 34485.0
The remainder is 12 after subtracting 1295 from 1307.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 259

Let's proceed to step 8:
If we divide 124 by 259, we get 0 and a remainder of 124.
The next digit of our result is 0. 
Result so far: 344850.0
Subtracting 0 from 124 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
If we divide 1240 by 259, we get 4 and a remainder of 204.
The next digit of our result is 4. 
Result so far: 344850.4
If we subtract 1036 from 1240, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
259 goes into 2040 7 times with a remainder of 227.
Use 7 as the next digit of our solution. 
Result so far: 344850.47
The remainder is 227 after subtracting 1813 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Advancing to step 11:
259 goes into 2270 8 times with a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 344850.478
The remainder is 198 after subtracting 2072 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 12:
259 goes into 1980 7 times with a remainder of 167.
Write down 7 as next digit of the result. 
Result so far: 344850.4787
The remainder is 167 after subtracting 1813 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 13:
259 can be fit into 1670 6 times, resulting in a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 344850.47876
If we subtract 1554 from 1670, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 14:
259 can be fit into 1160 4 times, resulting in a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 344850.478764
Subtracting 1036 from 1160 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 15:
When dividing 1240 by 259, we get 4 with a remainder of 204.
Record the quotient 4 as the next digit in the result. 
Result so far: 344850.4787644
Subtract 1036 from 1240 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 344850.4787644, with a leftover of 2.04e-06.
