Let's see how many times 39 fits into 90098405.

On to step 1:
9 divided by 39 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 39

Moving on to step 2:
If we divide 90 by 39, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 78 from 90 and we're left with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 39

Moving on to step 3:
120 divided by 39 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 3 after subtracting 117 from 120.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 39

Let's proceed to step 4:
If we divide 39 by 39, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 231.0
Subtract 39 from 39 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 39

Advancing to step 5:
The number 39 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 2310.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 39

On to step 6:
If we divide 84 by 39, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 23102.0
Subtracting 78 from 84 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 39

Let's proceed to step 7:
When dividing 60 by 39, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 231021.0
The remainder is 21 after subtracting 39 from 60.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 39

Going ahead to step 8:
When dividing 215 by 39, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 2310215.0
The remainder is 20 after subtracting 195 from 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 39 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2310215.5
Deduct 195 from 200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 39 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2310215.51
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
The number 39 fits into 110 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2310215.512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
The number 39 fits into 320 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 2310215.5128
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
39 can be fit into 80 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2310215.51282
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
The number 39 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2310215.51282
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
When dividing 200 by 39, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2310215.5128205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 16:
If we divide 50 by 39, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 2310215.51282051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 2310215.51282051 with a remaining 1.1e-08.
