98420507 ÷ 777 
We're looking to find how many times 777 goes into 98420507.

On to step 1:
9 divided by 777 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 777

On to step 2:
If we divide 98 by 777, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Grab the next digit (4) from the dividend, add it to 98, then carry on: 984 / 777

Moving on to step 3:
777 can be fit into 984 1 times, resulting in a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 777 away from 984, we end up with 207.
Append the next digit (2) from the dividend to 207 and continue with: 2072 / 777

Going ahead to step 4:
777 goes into 2072 2 times with a remainder of 518.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1554 from 2072 leaves us with 518.
Grab the next digit (0) from the dividend, add it to 518, then carry on: 5180 / 777

On to step 5:
The number 777 fits into 5180 6 times, leaving a remainder of 518.
Use 6 as the next digit of our solution. 
Result so far: 126.0
The remainder is 518 after subtracting 4662 from 5180.
Take the next digit (5) from the dividend and append it to 518, then repeat: 5185 / 777

Moving on to step 6:
777 can be fit into 5185 6 times, resulting in a remainder of 523.
Put 6 as the next digit of the answer. 
Result so far: 1266.0
The remainder is 523 after subtracting 4662 from 5185.
Fetch the next digit (0) from the dividend, attach it to 523 and continue: 5230 / 777

Advancing to step 7:
If we divide 5230 by 777, we get 6 and a remainder of 568.
The next digit of our result is 6. 
Result so far: 12666.0
If we subtract 4662 from 5230, we get 568.
Fetch the next digit (7) from the dividend, attach it to 568 and continue: 5687 / 777

On to step 8:
The number 777 fits into 5687 7 times, leaving a remainder of 248.
Use 7 as the next digit of our solution. 
Result so far: 126667.0
If we take 5439 away from 5687, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 9:
777 goes into 2480 3 times with a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 126667.3
If we take 2331 away from 2480, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 10:
777 can be fit into 1490 1 times, resulting in a remainder of 713.
Write down 1 as next digit of the result. 
Result so far: 126667.31
Subtract 777 from 1490 to get 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Let's proceed to step 11:
When dividing 7130 by 777, we get 9 with a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 126667.319
The remainder is 137 after subtracting 6993 from 7130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 12:
If we divide 1370 by 777, we get 1 and a remainder of 593.
Put 1 as the next digit of the answer. 
Result so far: 126667.3191
Deduct 777 from 1370 and we're left with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Advancing to step 13:
777 goes into 5930 7 times with a remainder of 491.
Put 7 as the next digit of the answer. 
Result so far: 126667.31917
Subtract 5439 from 5930 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Let's proceed to step 14:
4910 divided by 777 is 6 with a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 126667.319176
The remainder is 248 after subtracting 4662 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 15:
When dividing 2480 by 777, we get 3 with a remainder of 149.
Record the quotient 3 as the next digit in the result. 
Result so far: 126667.3191763
If we take 2331 away from 2480, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 16:
777 goes into 1490 1 times with a remainder of 713.
Put 1 as the next digit of the answer. 
Result so far: 126667.31917631
If we subtract 777 from 1490, we get 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

The final result is 126667.31917631 with a remainder of 7.13e-07.
