We're dividing 10257664 by 789 
Let's see how many times 789 fits into 10257664.

Moving on to step 1:
If we divide 1 by 789, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 789

Going ahead to step 2:
10 divided by 789 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 789

Going ahead to step 3:
When dividing 102 by 789, we get 0 with a remainder of 102.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 102 and we're left with 102.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 789

Advancing to step 4:
1025 divided by 789 is 1 with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 789 away from 1025, we end up with 236.
Bring next digit (7) of the dividend behind the 236 and repeat the process: 2367 / 789

Let's proceed to step 5:
When dividing 2367 by 789, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 2367 from 2367, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 789

Step 6:
The number 789 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 130.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 789

Going ahead to step 7:
789 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 1300.0
Subtract 0 from 66 to get 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 789

On to step 8:
789 goes into 664 0 times with a remainder of 664.
Record the quotient 0 as the next digit in the result. 
Result so far: 13000.0
The remainder is 664 after subtracting 0 from 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Going ahead to step 9:
If we divide 6640 by 789, we get 8 and a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 13000.8
Subtract 6312 from 6640 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
The number 789 fits into 3280 4 times, leaving a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 13000.84
Subtracting 3156 from 3280 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
If we divide 1240 by 789, we get 1 and a remainder of 451.
Use 1 as the next digit of our solution. 
Result so far: 13000.841
If we take 789 away from 1240, we end up with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 12:
4510 divided by 789 is 5 with a remainder of 565.
Write down 5 as next digit of the result. 
Result so far: 13000.8415
Deduct 3945 from 4510 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 13:
789 goes into 5650 7 times with a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 13000.84157
If we subtract 5523 from 5650, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 14:
1270 divided by 789 is 1 with a remainder of 481.
Record the quotient 1 as the next digit in the result. 
Result so far: 13000.841571
Subtract 789 from 1270 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Going ahead to step 15:
4810 divided by 789 is 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 13000.8415716
If we take 4734 away from 4810, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
If we divide 760 by 789, we get 0 and a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 13000.8415716
The remainder is 760 after subtracting 0 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The final outcome is 13000.8415716, with a leftover of 7.6e-07.
