77434564 divided by 89 
We want to divide 77434564 by 89.

Going ahead to step 1:
89 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 89

On to step 2:
77 divided by 89 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 89

Going ahead to step 3:
The number 89 fits into 774 8 times, leaving a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 712 away from 774, we end up with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 89

Moving on to step 4:
When dividing 623 by 89, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 623 from 623 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 89

Advancing to step 5:
4 divided by 89 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 870.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 89

Going ahead to step 6:
If we divide 45 by 89, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 8700.0
Subtract 0 from 45 to get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 89

On to step 7:
When dividing 456 by 89, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 87005.0
If we subtract 445 from 456, we get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 89

Advancing to step 8:
89 goes into 114 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 870051.0
Subtracting 89 from 114 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 89, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 870051.2
Deduct 178 from 250 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
720 divided by 89 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 870051.28
If we take 712 away from 720, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
80 divided by 89 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 870051.28
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
The number 89 fits into 800 8 times, leaving a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 870051.2808
If we take 712 away from 800, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 13:
If we divide 880 by 89, we get 9 and a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 870051.28089
Subtracting 801 from 880 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 14:
If we divide 790 by 89, we get 8 and a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 870051.280898
Subtracting 712 from 790 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 15:
780 divided by 89 is 8 with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 870051.2808988
Subtracting 712 from 780 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 870051.2808988, and the remainder is 6.8e-07.
