We're dividing 170961 by 77 
We want to divide 170961 by 77.

Advancing to step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 77

Advancing to step 2:
The number 77 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 77

Step 3:
170 divided by 77 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 154 from 170 leaves us with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 77

Advancing to step 4:
169 divided by 77 is 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 154 from 169 and we're left with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 77

Moving on to step 5:
When dividing 156 by 77, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 222.0
Deduct 154 from 156 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 77

On to step 6:
The number 77 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 2220.0
The remainder is 21 after subtracting 0 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
77 can be fit into 210 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 2220.2
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
560 divided by 77 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 2220.27
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 77, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 2220.272
The remainder is 56 after subtracting 154 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
When dividing 560 by 77, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 2220.2727
The remainder is 21 after subtracting 539 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
77 goes into 210 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 2220.27272
The remainder is 56 after subtracting 154 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
77 can be fit into 560 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 2220.272727
Subtract 539 from 560 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
If we divide 210 by 77, we get 2 and a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 2220.2727272
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
The number 77 fits into 560 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 2220.27272727
The remainder is 21 after subtracting 539 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 2220.27272727 with a remainder of 2.1e-08.
