Let's divide 89649964 by 7
Let's see how many times 7 fits into 89649964.

Going ahead to step 1:
7 goes into 8 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Moving on to step 2:
7 can be fit into 19 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 12.0
If we take 14 away from 19, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Step 3:
If we divide 56 by 7, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 56 from 56 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 7

Step 4:
4 divided by 7 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1280.0
If we take 0 away from 4, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 7

Going ahead to step 5:
If we divide 49 by 7, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 12807.0
Deduct 49 from 49 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 7

Let's proceed to step 6:
The number 7 fits into 9 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 128071.0
Subtracting 7 from 9 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 7

On to step 7:
If we divide 26 by 7, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1280713.0
The remainder is 5 after subtracting 21 from 26.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 7

Advancing to step 8:
54 divided by 7 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 12807137.0
If we take 49 away from 54, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 12807137.7
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 12807137.71
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 12807137.714
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12807137.7142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 12807137.71428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12807137.714285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 15:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 12807137.7142857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 16:
When dividing 10 by 7, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 12807137.71428571
Subtracting 7 from 10 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 12807137.71428571, and the remainder is 3e-09.
