We're dividing 98406421 by 259 
Let's see how many times 259 fits into 98406421.

Let's proceed to step 1:
9 divided by 259 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 259

Step 2:
The number 259 fits into 98 0 times, leaving a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Bring next digit (4) of the dividend behind the 98 and repeat the process: 984 / 259

Moving on to step 3:
When dividing 984 by 259, we get 3 with a remainder of 207.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 777 from 984 leaves us with 207.
Grab the next digit (0) from the dividend, add it to 207, then carry on: 2070 / 259

Moving on to step 4:
The number 259 fits into 2070 7 times, leaving a remainder of 257.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Deduct 1813 from 2070 and we're left with 257.
Grab the next digit (6) from the dividend, add it to 257, then carry on: 2576 / 259

Going ahead to step 5:
259 goes into 2576 9 times with a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 379.0
If we subtract 2331 from 2576, we get 245.
Bring next digit (4) of the dividend behind the 245 and repeat the process: 2454 / 259

Let's proceed to step 6:
The number 259 fits into 2454 9 times, leaving a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 3799.0
Subtracting 2331 from 2454 leaves us with 123.
Include the next digit (2) from the dividend after 123, then repeat: 1232 / 259

Step 7:
259 can be fit into 1232 4 times, resulting in a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 37994.0
If we take 1036 away from 1232, we end up with 196.
Append the next digit (1) from the dividend to 196 and continue with: 1961 / 259

Going ahead to step 8:
When dividing 1961 by 259, we get 7 with a remainder of 148.
Use 7 as the next digit of our solution. 
Result so far: 379947.0
Subtracting 1813 from 1961 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 9:
When dividing 1480 by 259, we get 5 with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 379947.5
The remainder is 185 after subtracting 1295 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 10:
259 goes into 1850 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 379947.57
If we subtract 1813 from 1850, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
259 goes into 370 1 times with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 379947.571
Subtracting 259 from 370 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 12:
259 can be fit into 1110 4 times, resulting in a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 379947.5714
If we take 1036 away from 1110, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
259 goes into 740 2 times with a remainder of 222.
The next digit of our result is 2. 
Result so far: 379947.57142
Subtract 518 from 740 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 14:
If we divide 2220 by 259, we get 8 and a remainder of 148.
Write down 8 as next digit of the result. 
Result so far: 379947.571428
Subtracting 2072 from 2220 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 15:
When dividing 1480 by 259, we get 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 379947.5714285
If we take 1295 away from 1480, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 16:
259 goes into 1850 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 379947.57142857
Subtracting 1813 from 1850 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 379947.57142857 with a remainder of 3.7e-08.
