61905789 ÷ 891 
We want to figure out the number of times 61905789 can be divided by 891.

Step 1:
6 divided by 891 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 891

On to step 2:
891 can be fit into 61 0 times, resulting in a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 891

On to step 3:
The number 891 fits into 619 0 times, leaving a remainder of 619.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 619 and we're left with 619.
Bring next digit (0) of the dividend behind the 619 and repeat the process: 6190 / 891

Step 4:
891 can be fit into 6190 6 times, resulting in a remainder of 844.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 5346 from 6190 leaves us with 844.
Include the next digit (5) from the dividend after 844, then repeat: 8445 / 891

Going ahead to step 5:
891 can be fit into 8445 9 times, resulting in a remainder of 426.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we take 8019 away from 8445, we end up with 426.
Fetch the next digit (7) from the dividend, attach it to 426 and continue: 4267 / 891

Let's proceed to step 6:
891 can be fit into 4267 4 times, resulting in a remainder of 703.
The next digit of our result is 4. 
Result so far: 694.0
If we subtract 3564 from 4267, we get 703.
Grab the next digit (8) from the dividend, add it to 703, then carry on: 7038 / 891

Going ahead to step 7:
The number 891 fits into 7038 7 times, leaving a remainder of 801.
Put 7 as the next digit of the answer. 
Result so far: 6947.0
The remainder is 801 after subtracting 6237 from 7038.
Grab the next digit (9) from the dividend, add it to 801, then carry on: 8019 / 891

Moving on to step 8:
891 goes into 8019 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 69479.0
If we take 8019 away from 8019, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 891 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 69479.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 891, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 69479.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 69479.0 with a balance of 0.0.
