98587172 divided by 399 
We want to figure out the number of times 98587172 can be divided by 399.

Advancing to step 1:
9 divided by 399 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 399

Let's proceed to step 2:
When dividing 98 by 399, we get 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 399

Let's proceed to step 3:
If we divide 985 by 399, we get 2 and a remainder of 187.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 798 from 985 to get 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 399

Step 4:
399 goes into 1878 4 times with a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 1596 away from 1878, we end up with 282.
Grab the next digit (7) from the dividend, add it to 282, then carry on: 2827 / 399

Going ahead to step 5:
2827 divided by 399 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 247.0
If we take 2793 away from 2827, we end up with 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 399

On to step 6:
When dividing 341 by 399, we get 0 with a remainder of 341.
Use 0 as the next digit of our solution. 
Result so far: 2470.0
If we take 0 away from 341, we end up with 341.
Grab the next digit (7) from the dividend, add it to 341, then carry on: 3417 / 399

Advancing to step 7:
If we divide 3417 by 399, we get 8 and a remainder of 225.
Write down 8 as next digit of the result. 
Result so far: 24708.0
Subtracting 3192 from 3417 leaves us with 225.
Append the next digit (2) from the dividend to 225 and continue with: 2252 / 399

Advancing to step 8:
When dividing 2252 by 399, we get 5 with a remainder of 257.
Use 5 as the next digit of our solution. 
Result so far: 247085.0
Subtracting 1995 from 2252 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 9:
399 goes into 2570 6 times with a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 247085.6
If we subtract 2394 from 2570, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 10:
1760 divided by 399 is 4 with a remainder of 164.
Record the quotient 4 as the next digit in the result. 
Result so far: 247085.64
Subtract 1596 from 1760 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
When dividing 1640 by 399, we get 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 247085.644
If we subtract 1596 from 1640, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 247085.644 with a remaining 0.0044.
