We look at the division of 88961 by 77 
Let's see how many times 77 fits into 88961.

Going ahead to step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 77

Moving on to step 2:
88 divided by 77 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 11 after subtracting 77 from 88.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 77

On to step 3:
The number 77 fits into 119 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 77 from 119 and we're left with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 77

Let's proceed to step 4:
77 can be fit into 426 5 times, resulting in a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we take 385 away from 426, we end up with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 77

Going ahead to step 5:
When dividing 411 by 77, we get 5 with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 1155.0
Subtracting 385 from 411 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 6:
When dividing 260 by 77, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 1155.3
Deduct 231 from 260 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 77 fits into 290 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 1155.33
If we take 231 away from 290, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 1155.33, with a leftover of 0.059.
