Let's divide 79478666 by 89
We're looking to find how many times 89 goes into 79478666.

Advancing to step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 89

Let's proceed to step 2:
89 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 89

On to step 3:
89 can be fit into 794 8 times, resulting in a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 712 from 794 leaves us with 82.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 89

Let's proceed to step 4:
89 can be fit into 827 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 89.0
Subtract 801 from 827 to get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 89

Let's proceed to step 5:
When dividing 268 by 89, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 893.0
Subtracting 267 from 268 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 89

Let's proceed to step 6:
The number 89 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 8930.0
Subtract 0 from 16 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 89

On to step 7:
89 goes into 166 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 89301.0
Subtract 89 from 166 to get 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 89

On to step 8:
The number 89 fits into 776 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 893018.0
Deduct 712 from 776 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
If we divide 640 by 89, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 893018.7
Subtracting 623 from 640 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
The number 89 fits into 170 1 times, leaving a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 893018.71
Subtract 89 from 170 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 11:
810 divided by 89 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 893018.719
If we subtract 801 from 810, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
90 divided by 89 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 893018.7191
The remainder is 1 after subtracting 89 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
If we divide 10 by 89, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 893018.7191
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 89, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 893018.719101
Subtracting 89 from 100 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 15:
110 divided by 89 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 893018.7191011
If we take 89 away from 110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 893018.7191011 with a balance of 2.1e-07.
