Let's divide 77189859 by 89
We want to figure out the number of times 77189859 can be divided by 89.

Moving on to step 1:
The number 89 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 89

Step 2:
89 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 89

Going ahead to step 3:
771 divided by 89 is 8 with a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 712 away from 771, we end up with 59.
Fetch the next digit (8) from the dividend, attach it to 59 and continue: 598 / 89

Going ahead to step 4:
If we divide 598 by 89, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 534 from 598 and we're left with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 89

Let's proceed to step 5:
If we divide 649 by 89, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 867.0
Deduct 623 from 649 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 89

On to step 6:
If we divide 268 by 89, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 8673.0
If we take 267 away from 268, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 89

On to step 7:
The number 89 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 86730.0
If we subtract 0 from 15, we get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 89

Let's proceed to step 8:
When dividing 159 by 89, we get 1 with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 867301.0
If we subtract 89 from 159, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
89 can be fit into 700 7 times, resulting in a remainder of 77.
The next digit of our result is 7. 
Result so far: 867301.7
If we subtract 623 from 700, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 10:
770 divided by 89 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 867301.78
Subtract 712 from 770 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
89 can be fit into 580 6 times, resulting in a remainder of 46.
The next digit of our result is 6. 
Result so far: 867301.786
If we subtract 534 from 580, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
89 can be fit into 460 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 867301.7865
Subtract 445 from 460 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
150 divided by 89 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 867301.78651
If we subtract 89 from 150, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
89 can be fit into 610 6 times, resulting in a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 867301.786516
Subtract 534 from 610 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
When dividing 760 by 89, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 867301.7865168
If we subtract 712 from 760, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 16:
When dividing 480 by 89, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 867301.78651685
If we subtract 445 from 480, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 867301.78651685 with a balance of 3.5e-08.
