We look at the division of 18251589 by 777 
We want to figure out the number of times 18251589 can be divided by 777.

Going ahead to step 1:
777 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 777

On to step 2:
777 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 777

Moving on to step 3:
When dividing 182 by 777, we get 0 with a remainder of 182.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 182, we end up with 182.
Include the next digit (5) from the dividend after 182, then repeat: 1825 / 777

Let's proceed to step 4:
1825 divided by 777 is 2 with a remainder of 271.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 271 after subtracting 1554 from 1825.
Include the next digit (1) from the dividend after 271, then repeat: 2711 / 777

Advancing to step 5:
The number 777 fits into 2711 3 times, leaving a remainder of 380.
The next digit of our result is 3. 
Result so far: 23.0
If we take 2331 away from 2711, we end up with 380.
Append the next digit (5) from the dividend to 380 and continue with: 3805 / 777

Going ahead to step 6:
777 can be fit into 3805 4 times, resulting in a remainder of 697.
Write down 4 as next digit of the result. 
Result so far: 234.0
The remainder is 697 after subtracting 3108 from 3805.
Bring next digit (8) of the dividend behind the 697 and repeat the process: 6978 / 777

Going ahead to step 7:
If we divide 6978 by 777, we get 8 and a remainder of 762.
Write down 8 as next digit of the result. 
Result so far: 2348.0
Subtract 6216 from 6978 to get 762.
Take the next digit (9) from the dividend and append it to 762, then repeat: 7629 / 777

On to step 8:
777 goes into 7629 9 times with a remainder of 636.
Use 9 as the next digit of our solution. 
Result so far: 23489.0
The remainder is 636 after subtracting 6993 from 7629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 9:
777 goes into 6360 8 times with a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 23489.8
If we take 6216 away from 6360, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 10:
1440 divided by 777 is 1 with a remainder of 663.
Put 1 as the next digit of the answer. 
Result so far: 23489.81
If we subtract 777 from 1440, we get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

On to step 11:
6630 divided by 777 is 8 with a remainder of 414.
Use 8 as the next digit of our solution. 
Result so far: 23489.818
The remainder is 414 after subtracting 6216 from 6630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 12:
When dividing 4140 by 777, we get 5 with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 23489.8185
Subtracting 3885 from 4140 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 13:
777 can be fit into 2550 3 times, resulting in a remainder of 219.
The number 3 becomes the next digit in our result. 
Result so far: 23489.81853
If we subtract 2331 from 2550, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 14:
If we divide 2190 by 777, we get 2 and a remainder of 636.
The number 2 becomes the next digit in our result. 
Result so far: 23489.818532
Subtracting 1554 from 2190 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 15:
777 goes into 6360 8 times with a remainder of 144.
Record the quotient 8 as the next digit in the result. 
Result so far: 23489.8185328
Subtracting 6216 from 6360 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 16:
777 can be fit into 1440 1 times, resulting in a remainder of 663.
The next digit of our result is 1. 
Result so far: 23489.81853281
If we take 777 away from 1440, we end up with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

The final outcome is 23489.81853281, with a leftover of 6.63e-07.
