Append the next digit (7) from the dividend to 7 and continue with: 77 / 891

Advancing to step 2:
891 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 891

Moving on to step 3:
891 goes into 775 0 times with a remainder of 775.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 775 after subtracting 0 from 775.
Grab the next digit (8) from the dividend, add it to 775, then carry on: 7758 / 891

On to step 4:
891 can be fit into 7758 8 times, resulting in a remainder of 630.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7128 from 7758, we get 630.
Include the next digit (7) from the dividend after 630, then repeat: 6307 / 891

Going ahead to step 5:
891 goes into 6307 7 times with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 6237 from 6307 and we're left with 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 891

Advancing to step 6:
891 goes into 702 0 times with a remainder of 702.
Put 0 as the next digit of the answer. 
Result so far: 870.0
If we subtract 0 from 702, we get 702.
Include the next digit (5) from the dividend after 702, then repeat: 7025 / 891

Moving on to step 7:
891 can be fit into 7025 7 times, resulting in a remainder of 788.
Put 7 as the next digit of the answer. 
Result so far: 8707.0
Subtracting 6237 from 7025 leaves us with 788.
Grab the next digit (2) from the dividend, add it to 788, then carry on: 7882 / 891

Moving on to step 8:
The number 891 fits into 7882 8 times, leaving a remainder of 754.
Put 8 as the next digit of the answer. 
Result so far: 87078.0
Deduct 7128 from 7882 and we're left with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Advancing to step 9:
When dividing 7540 by 891, we get 8 with a remainder of 412.
The next digit of our result is 8. 
Result so far: 87078.8
The remainder is 412 after subtracting 7128 from 7540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 10:
891 can be fit into 4120 4 times, resulting in a remainder of 556.
The next digit of our result is 4. 
Result so far: 87078.84
If we take 3564 away from 4120, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 11:
5560 divided by 891 is 6 with a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 87078.846
If we take 5346 away from 5560, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 12:
If we divide 2140 by 891, we get 2 and a remainder of 358.
The number 2 becomes the next digit in our result. 
Result so far: 87078.8462
The remainder is 358 after subtracting 1782 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 13:
If we divide 3580 by 891, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 87078.84624
If we subtract 3564 from 3580, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
160 divided by 891 is 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 87078.84624
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
When dividing 1600 by 891, we get 1 with a remainder of 709.
Record the quotient 1 as the next digit in the result. 
Result so far: 87078.8462401
Subtracting 891 from 1600 leaves us with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Moving on to step 16:
7090 divided by 891 is 7 with a remainder of 853.
The number 7 becomes the next digit in our result. 
Result so far: 87078.84624017
If we take 6237 away from 7090, we end up with 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

In conclusion, the division gives 87078.84624017 with a balance of 8.53e-07.
