98547089 divided by 409 
Our goal is to divide 98547089 by 409.

Advancing to step 1:
409 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 409

On to step 2:
When dividing 98 by 409, we get 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 409

Advancing to step 3:
409 can be fit into 985 2 times, resulting in a remainder of 167.
Put 2 as the next digit of the answer. 
Result so far: 2.0

Fetch the next digit (4) from the dividend, attach it to 167 and continue: 1674 / 409

Advancing to step 4:
1674 divided by 409 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtracting 1636 from 1674 leaves us with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 409

On to step 5:
The number 409 fits into 387 0 times, leaving a remainder of 387.
Put 0 as the next digit of the answer. 
Result so far: 240.0
If we take 0 away from 387, we end up with 387.
Bring next digit (0) of the dividend behind the 387 and repeat the process: 3870 / 409

Advancing to step 6:
If we divide 3870 by 409, we get 9 and a remainder of 189.
Write down 9 as next digit of the result. 
Result so far: 2409.0
Deduct 3681 from 3870 and we're left with 189.
Append the next digit (8) from the dividend to 189 and continue with: 1898 / 409

Moving on to step 7:
The number 409 fits into 1898 4 times, leaving a remainder of 262.
The next digit of our result is 4. 
Result so far: 24094.0
Deduct 1636 from 1898 and we're left with 262.
Grab the next digit (9) from the dividend, add it to 262, then carry on: 2629 / 409

On to step 8:
If we divide 2629 by 409, we get 6 and a remainder of 175.
The next digit of our result is 6. 
Result so far: 240946.0
Subtracting 2454 from 2629 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 9:
If we divide 1750 by 409, we get 4 and a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 240946.4
If we take 1636 away from 1750, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 10:
The number 409 fits into 1140 2 times, leaving a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 240946.42
Deduct 818 from 1140 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 11:
If we divide 3220 by 409, we get 7 and a remainder of 357.
Write down 7 as next digit of the result. 
Result so far: 240946.427
Subtract 2863 from 3220 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 12:
409 can be fit into 3570 8 times, resulting in a remainder of 298.
The next digit of our result is 8. 
Result so far: 240946.4278
If we take 3272 away from 3570, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 13:
If we divide 2980 by 409, we get 7 and a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 240946.42787
If we subtract 2863 from 2980, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 14:
409 goes into 1170 2 times with a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 240946.427872
Deduct 818 from 1170 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 15:
409 goes into 3520 8 times with a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 240946.4278728
Subtract 3272 from 3520 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 16:
2480 divided by 409 is 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 240946.42787286
Subtracting 2454 from 2480 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 240946.42787286, with a leftover of 2.6e-08.
