18407158 divided by 439 
We want to divide 18407158 by 439.

Step 1:
When dividing 1 by 439, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 439

Moving on to step 2:
When dividing 18 by 439, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 439

Going ahead to step 3:
439 can be fit into 184 0 times, resulting in a remainder of 184.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 184 leaves us with 184.
Take the next digit (0) from the dividend and append it to 184, then repeat: 1840 / 439

Going ahead to step 4:
439 can be fit into 1840 4 times, resulting in a remainder of 84.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 84 after subtracting 1756 from 1840.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 439

On to step 5:
847 divided by 439 is 1 with a remainder of 408.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 408 after subtracting 439 from 847.
Bring next digit (1) of the dividend behind the 408 and repeat the process: 4081 / 439

Step 6:
When dividing 4081 by 439, we get 9 with a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 419.0
Deduct 3951 from 4081 and we're left with 130.
Bring next digit (5) of the dividend behind the 130 and repeat the process: 1305 / 439

Step 7:
439 goes into 1305 2 times with a remainder of 427.
The next digit of our result is 2. 
Result so far: 4192.0
Deduct 878 from 1305 and we're left with 427.
Grab the next digit (8) from the dividend, add it to 427, then carry on: 4278 / 439

Let's proceed to step 8:
439 goes into 4278 9 times with a remainder of 327.
Put 9 as the next digit of the answer. 
Result so far: 41929.0
If we subtract 3951 from 4278, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 9:
439 goes into 3270 7 times with a remainder of 197.
The next digit of our result is 7. 
Result so far: 41929.7
Subtract 3073 from 3270 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 10:
439 can be fit into 1970 4 times, resulting in a remainder of 214.
Use 4 as the next digit of our solution. 
Result so far: 41929.74
If we subtract 1756 from 1970, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 11:
439 goes into 2140 4 times with a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 41929.744
The remainder is 384 after subtracting 1756 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The quotient of the division is 41929.744, and the remainder is 0.0384.
