56816578 ÷ 891 
We want to divide 56816578 by 891.

Step 1:
891 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 891

Moving on to step 2:
56 divided by 891 is 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 891

Step 3:
The number 891 fits into 568 0 times, leaving a remainder of 568.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 568, we end up with 568.
Fetch the next digit (1) from the dividend, attach it to 568 and continue: 5681 / 891

Let's proceed to step 4:
The number 891 fits into 5681 6 times, leaving a remainder of 335.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5346 from 5681 leaves us with 335.
Fetch the next digit (6) from the dividend, attach it to 335 and continue: 3356 / 891

Advancing to step 5:
891 can be fit into 3356 3 times, resulting in a remainder of 683.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtract 2673 from 3356 to get 683.
Include the next digit (5) from the dividend after 683, then repeat: 6835 / 891

Moving on to step 6:
6835 divided by 891 is 7 with a remainder of 598.
Use 7 as the next digit of our solution. 
Result so far: 637.0
If we take 6237 away from 6835, we end up with 598.
Grab the next digit (7) from the dividend, add it to 598, then carry on: 5987 / 891

On to step 7:
891 goes into 5987 6 times with a remainder of 641.
The number 6 becomes the next digit in our result. 
Result so far: 6376.0
Subtract 5346 from 5987 to get 641.
Grab the next digit (8) from the dividend, add it to 641, then carry on: 6418 / 891

On to step 8:
6418 divided by 891 is 7 with a remainder of 181.
Write down 7 as next digit of the result. 
Result so far: 63767.0
Subtracting 6237 from 6418 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
891 can be fit into 1810 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 63767.2
Subtracting 1782 from 1810 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
The number 891 fits into 280 0 times, leaving a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 63767.2
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
891 goes into 2800 3 times with a remainder of 127.
The next digit of our result is 3. 
Result so far: 63767.203
The remainder is 127 after subtracting 2673 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
891 can be fit into 1270 1 times, resulting in a remainder of 379.
The next digit of our result is 1. 
Result so far: 63767.2031
Subtracting 891 from 1270 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 13:
The number 891 fits into 3790 4 times, leaving a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 63767.20314
The remainder is 226 after subtracting 3564 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 14:
891 goes into 2260 2 times with a remainder of 478.
Put 2 as the next digit of the answer. 
Result so far: 63767.203142
The remainder is 478 after subtracting 1782 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 15:
891 can be fit into 4780 5 times, resulting in a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 63767.2031425
Subtract 4455 from 4780 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 16:
891 can be fit into 3250 3 times, resulting in a remainder of 577.
Use 3 as the next digit of our solution. 
Result so far: 63767.20314253
Subtract 2673 from 3250 to get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

After the division, we end up with 63767.20314253 and a remainder of 5.77e-07.
