We divide 12590770 by 104
We want to figure out the number of times 12590770 can be divided by 104.

Let's proceed to step 1:
104 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 104

On to step 2:
104 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 104

On to step 3:
104 goes into 125 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 104 from 125, we get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 104

Moving on to step 4:
219 divided by 104 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 208 from 219 and we're left with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 104

Let's proceed to step 5:
110 divided by 104 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we take 104 away from 110, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 104

Step 6:
If we divide 67 by 104, we get 0 and a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 1210.0
Subtract 0 from 67 to get 67.
Bring next digit (7) of the dividend behind the 67 and repeat the process: 677 / 104

Step 7:
If we divide 677 by 104, we get 6 and a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 12106.0
The remainder is 53 after subtracting 624 from 677.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 104

Going ahead to step 8:
104 can be fit into 530 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 121065.0
If we take 520 away from 530, we end up 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.

Step 9:
The number 104 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 121065.0
Subtract 0 from 100 to 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.

Moving on to step 10:
If we divide 1000 by 104, we get 9 and a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 121065.09
If we take 936 away from 1000, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
104 goes into 640 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 121065.096
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
If we divide 160 by 104, we get 1 and a remainder of 56.
The next digit of our result is 1. 
Result so far: 121065.0961
The remainder is 56 after subtracting 104 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
If we divide 560 by 104, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 121065.09615
The remainder is 40 after subtracting 520 from 560.
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 14:
The number 104 fits into 400 3 times, leaving a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 121065.096153
Subtract 312 from 400 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 15:
880 divided by 104 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 121065.0961538
Subtract 832 from 880 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 16:
The number 104 fits into 480 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 121065.09615384
If we subtract 416 from 480, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 121065.09615384, and the remainder is 6.4e-08.
