We look at the division of 77981357 by 462 
We're looking to find how many times 462 goes into 77981357.

Advancing to step 1:
462 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 462

Step 2:
If we divide 77 by 462, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 462

Step 3:
779 divided by 462 is 1 with a remainder of 317.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 462 from 779, we get 317.
Append the next digit (8) from the dividend to 317 and continue with: 3178 / 462

Moving on to step 4:
When dividing 3178 by 462, we get 6 with a remainder of 406.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 2772 from 3178 and we're left with 406.
Take the next digit (1) from the dividend and append it to 406, then repeat: 4061 / 462

Step 5:
462 can be fit into 4061 8 times, resulting in a remainder of 365.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we subtract 3696 from 4061, we get 365.
Append the next digit (3) from the dividend to 365 and continue with: 3653 / 462

On to step 6:
The number 462 fits into 3653 7 times, leaving a remainder of 419.
The number 7 becomes the next digit in our result. 
Result so far: 1687.0
If we take 3234 away from 3653, we end up with 419.
Include the next digit (5) from the dividend after 419, then repeat: 4195 / 462

On to step 7:
462 goes into 4195 9 times with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 16879.0
Subtract 4158 from 4195 to get 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 462

Moving on to step 8:
377 divided by 462 is 0 with a remainder of 377.
The next digit of our result is 0. 
Result so far: 168790.0
Subtract 0 from 377 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 9:
When dividing 3770 by 462, we get 8 with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 168790.8
Subtract 3696 from 3770 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
The number 462 fits into 740 1 times, leaving a remainder of 278.
The next digit of our result is 1. 
Result so far: 168790.81
Subtracting 462 from 740 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 11:
If we divide 2780 by 462, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 168790.816
If we take 2772 away from 2780, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
When dividing 80 by 462, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 168790.816
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
When dividing 800 by 462, we get 1 with a remainder of 338.
Use 1 as the next digit of our solution. 
Result so far: 168790.81601
If we take 462 away from 800, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 14:
462 can be fit into 3380 7 times, resulting in a remainder of 146.
Use 7 as the next digit of our solution. 
Result so far: 168790.816017
The remainder is 146 after subtracting 3234 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 15:
462 can be fit into 1460 3 times, resulting in a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 168790.8160173
The remainder is 74 after subtracting 1386 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 16:
If we divide 740 by 462, we get 1 and a remainder of 278.
Record the quotient 1 as the next digit in the result. 
Result so far: 168790.81601731
If we subtract 462 from 740, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final outcome is 168790.81601731, with a leftover of 2.78e-07.
