We're dividing 91557211 by 259 
Let's see how many times 259 fits into 91557211.

Step 1:
The number 259 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 259

On to step 2:
The number 259 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 259

Advancing to step 3:
The number 259 fits into 915 3 times, leaving a remainder of 138.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 777 from 915 to get 138.
Include the next digit (5) from the dividend after 138, then repeat: 1385 / 259

Step 4:
259 can be fit into 1385 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 1295 from 1385 to get 90.
Grab the next digit (7) from the dividend, add it to 90, then carry on: 907 / 259

On to step 5:
If we divide 907 by 259, we get 3 and a remainder of 130.
The next digit of our result is 3. 
Result so far: 353.0
Subtracting 777 from 907 leaves us with 130.
Take the next digit (2) from the dividend and append it to 130, then repeat: 1302 / 259

Step 6:
If we divide 1302 by 259, we get 5 and a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 3535.0
Deduct 1295 from 1302 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 259

Moving on to step 7:
The number 259 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 35350.0
Subtract 0 from 71 to get 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 259

Going ahead to step 8:
711 divided by 259 is 2 with a remainder of 193.
Use 2 as the next digit of our solution. 
Result so far: 353502.0
If we take 518 away from 711, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 9:
When dividing 1930 by 259, we get 7 with a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 353502.7
If we take 1813 away from 1930, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 10:
If we divide 1170 by 259, we get 4 and a remainder of 134.
The next digit of our result is 4. 
Result so far: 353502.74
Subtracting 1036 from 1170 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 11:
If we divide 1340 by 259, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 353502.745
Subtracting 1295 from 1340 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
When dividing 450 by 259, we get 1 with a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 353502.7451
If we subtract 259 from 450, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 13:
259 can be fit into 1910 7 times, resulting in a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 353502.74517
Deduct 1813 from 1910 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 14:
If we divide 970 by 259, we get 3 and a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 353502.745173
If we take 777 away from 970, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 15:
When dividing 1930 by 259, we get 7 with a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 353502.7451737
The remainder is 117 after subtracting 1813 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 16:
1170 divided by 259 is 4 with a remainder of 134.
Use 4 as the next digit of our solution. 
Result so far: 353502.74517374
Deduct 1036 from 1170 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 353502.74517374 and a remainder of 1.34e-07.
