We look at the division of 91039830 by 439 
Our goal is to divide 91039830 by 439.

Going ahead to step 1:
439 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 439

Advancing to step 2:
91 divided by 439 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 439

Advancing to step 3:
If we divide 910 by 439, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 878 from 910 leaves us with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 439

Going ahead to step 4:
The number 439 fits into 323 0 times, leaving a remainder of 323.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 323, we get 323.
Take the next digit (9) from the dividend and append it to 323, then repeat: 3239 / 439

Let's proceed to step 5:
439 can be fit into 3239 7 times, resulting in a remainder of 166.
Write down 7 as next digit of the result. 
Result so far: 207.0
Subtract 3073 from 3239 to get 166.
Fetch the next digit (8) from the dividend, attach it to 166 and continue: 1668 / 439

Going ahead to step 6:
If we divide 1668 by 439, we get 3 and a remainder of 351.
Put 3 as the next digit of the answer. 
Result so far: 2073.0
The remainder is 351 after subtracting 1317 from 1668.
Append the next digit (3) from the dividend to 351 and continue with: 3513 / 439

Let's proceed to step 7:
439 can be fit into 3513 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 20738.0
If we subtract 3512 from 3513, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 439

On to step 8:
When dividing 10 by 439, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 207380.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
439 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 207380.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
When dividing 1000 by 439, we get 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 207380.02
Subtract 878 from 1000 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 11:
When dividing 1220 by 439, we get 2 with a remainder of 342.
Write down 2 as next digit of the result. 
Result so far: 207380.022
If we take 878 away from 1220, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final result is 207380.022 with a remainder of 0.0342.
