We divide 990358 by 77
Our goal is to divide 990358 by 77.

On to step 1:
77 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 77

Moving on to step 2:
If we divide 99 by 77, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 99 leaves us with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 77

Moving on to step 3:
The number 77 fits into 220 2 times, leaving a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 154 from 220 and we're left with 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 77

Moving on to step 4:
77 goes into 663 8 times with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 616 from 663 to get 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 77

On to step 5:
77 can be fit into 475 6 times, resulting in a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 1286.0
Subtracting 462 from 475 leaves us with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 77

Advancing to step 6:
138 divided by 77 is 1 with a remainder of 61.
The next digit of our result is 1. 
Result so far: 12861.0
Subtract 77 from 138 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
77 goes into 610 7 times with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 12861.7
If we take 539 away from 610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 8:
When dividing 710 by 77, we get 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 12861.79
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
The number 77 fits into 170 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12861.792
If we take 154 away from 170, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 77, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 12861.7922
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 12861.7922, with a leftover of 6e-05.
