We look at the division of 79998921 by 89 
We're looking to find how many times 89 goes into 79998921.

Advancing to step 1:
7 divided by 89 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 89

Going ahead to step 2:
79 divided by 89 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Grab the next digit (9) from the dividend, add it to 79, then carry on: 799 / 89

Advancing to step 3:
When dividing 799 by 89, we get 8 with a remainder of 87.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 712 from 799 to get 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 89

Step 4:
The number 89 fits into 879 9 times, leaving a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 801 away from 879, we end up with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 89

Step 5:
89 can be fit into 788 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 898.0
If we subtract 712 from 788, we get 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 89

On to step 6:
89 goes into 769 8 times with a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 8988.0
Subtract 712 from 769 to get 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 89

On to step 7:
89 goes into 572 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 89886.0
If we take 534 away from 572, we end up with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 89

Advancing to step 8:
89 can be fit into 381 4 times, resulting in a remainder of 25.
The next digit of our result is 4. 
Result so far: 898864.0
Deduct 356 from 381 and we're left 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:
The number 89 fits into 250 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 898864.2
The remainder is 72 after subtracting 178 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
89 goes into 720 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 898864.28
If we subtract 712 from 720, we get 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:
89 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 898864.28
Deduct 0 from 80 and we're left 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.

On to step 12:
The number 89 fits into 800 8 times, leaving a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 898864.2808
The remainder is 88 after subtracting 712 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
89 can be fit into 880 9 times, resulting in a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 898864.28089
Deduct 801 from 880 and we're left 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.

Advancing to step 14:
89 can be fit into 790 8 times, resulting in a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 898864.280898
The remainder is 78 after subtracting 712 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 15:
When dividing 780 by 89, we get 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 898864.2808988
If we take 712 away from 780, we end up 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.

After the division, we end up with 898864.2808988 and a remainder of 6.8e-07.
