We look at the division of 781898 by 77 
We want to divide 781898 by 77.

Let's proceed to step 1:
The number 77 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 77

Advancing to step 2:
78 divided by 77 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 78 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 77

Moving on to step 3:
77 goes into 11 0 times with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 11, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 77

Advancing to step 4:
77 goes into 118 1 times with a remainder of 41.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 77 from 118 leaves us with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 77

On to step 5:
77 goes into 419 5 times with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 1015.0
If we subtract 385 from 419, we get 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 77

Advancing to step 6:
348 divided by 77 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 10154.0
Subtracting 308 from 348 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
77 goes into 400 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10154.5
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 10154.51
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
730 divided by 77 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 10154.519
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
77 can be fit into 370 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 10154.5194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
77 can be fit into 620 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 10154.51948
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
77 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10154.51948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
77 can be fit into 400 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10154.5194805
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 10154.51948051
If we subtract 77 from 150, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

After the division, we end up with 10154.51948051 and a remainder of 7.3e-08.
