On to step 4:
2226 divided by 777 is 2 with a remainder of 672.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1554 from 2226 to get 672.
Grab the next digit (9) from the dividend, add it to 672, then carry on: 6729 / 777

Step 5:
When dividing 6729 by 777, we get 8 with a remainder of 513.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we subtract 6216 from 6729, we get 513.
Take the next digit (9) from the dividend and append it to 513, then repeat: 5139 / 777

Moving on to step 6:
5139 divided by 777 is 6 with a remainder of 477.
The number 6 becomes the next digit in our result. 
Result so far: 1286.0
Subtract 4662 from 5139 to get 477.
Fetch the next digit (8) from the dividend, attach it to 477 and continue: 4778 / 777

Going ahead to step 7:
The number 777 fits into 4778 6 times, leaving a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 12866.0
The remainder is 116 after subtracting 4662 from 4778.
Take the next digit (2) from the dividend and append it to 116, then repeat: 1162 / 777

Moving on to step 8:
777 goes into 1162 1 times with a remainder of 385.
Put 1 as the next digit of the answer. 
Result so far: 128661.0
Subtracting 777 from 1162 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 9:
The number 777 fits into 3850 4 times, leaving a remainder of 742.
Use 4 as the next digit of our solution. 
Result so far: 128661.4
Subtracting 3108 from 3850 leaves us with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Advancing to step 10:
777 goes into 7420 9 times with a remainder of 427.
Use 9 as the next digit of our solution. 
Result so far: 128661.49
If we take 6993 away from 7420, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 11:
777 goes into 4270 5 times with a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 128661.495
The remainder is 385 after subtracting 3885 from 4270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 12:
When dividing 3850 by 777, we get 4 with a remainder of 742.
The next digit of our result is 4. 
Result so far: 128661.4954
If we subtract 3108 from 3850, we get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 13:
When dividing 7420 by 777, we get 9 with a remainder of 427.
The next digit of our result is 9. 
Result so far: 128661.49549
Subtract 6993 from 7420 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Moving on to step 14:
When dividing 4270 by 777, we get 5 with a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 128661.495495
If we subtract 3885 from 4270, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 15:
The number 777 fits into 3850 4 times, leaving a remainder of 742.
Record the quotient 4 as the next digit in the result. 
Result so far: 128661.4954954
Deduct 3108 from 3850 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Moving on to step 16:
The number 777 fits into 7420 9 times, leaving a remainder of 427.
The number 9 becomes the next digit in our result. 
Result so far: 128661.49549549
Subtract 6993 from 7420 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

The final outcome is 128661.49549549, with a leftover of 4.27e-07.
