90663847 ÷ 260 
Our goal is to divide 90663847 by 260.

Moving on to step 1:
260 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 260

Let's proceed to step 2:
90 divided by 260 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 260

On to step 3:
The number 260 fits into 906 3 times, leaving a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 780 from 906 to get 126.
Fetch the next digit (6) from the dividend, attach it to 126 and continue: 1266 / 260

On to step 4:
The number 260 fits into 1266 4 times, leaving a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 1040 from 1266 leaves us with 226.
Bring next digit (3) of the dividend behind the 226 and repeat the process: 2263 / 260

On to step 5:
The number 260 fits into 2263 8 times, leaving a remainder of 183.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
Subtract 2080 from 2263 to get 183.
Bring next digit (8) of the dividend behind the 183 and repeat the process: 1838 / 260

Let's proceed to step 6:
260 can be fit into 1838 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 3487.0
If we subtract 1820 from 1838, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 260

Advancing to step 7:
When dividing 184 by 260, we get 0 with a remainder of 184.
Write down 0 as next digit of the result. 
Result so far: 34870.0
If we subtract 0 from 184, we get 184.
Grab the next digit (7) from the dividend, add it to 184, then carry on: 1847 / 260

Moving on to step 8:
260 can be fit into 1847 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 348707.0
Subtract 1820 from 1847 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
260 goes into 270 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 348707.1
The remainder is 10 after subtracting 260 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 260, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 348707.1
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
260 goes into 1000 3 times with a remainder of 220.
Put 3 as the next digit of the answer. 
Result so far: 348707.103
Subtracting 780 from 1000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 12:
If we divide 2200 by 260, we get 8 and a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 348707.1038
If we take 2080 away from 2200, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
The number 260 fits into 1200 4 times, leaving a remainder of 160.
The next digit of our result is 4. 
Result so far: 348707.10384
Deduct 1040 from 1200 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
The number 260 fits into 1600 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 348707.103846
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
260 can be fit into 400 1 times, resulting in a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 348707.1038461
If we take 260 away from 400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 16:
260 can be fit into 1400 5 times, resulting in a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 348707.10384615
Subtracting 1300 from 1400 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 348707.10384615 with a remainder of 1e-07.
