Let's divide 90636433 by 7
We want to divide 90636433 by 7.

Advancing to step 1:
If we divide 9 by 7, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 7 from 9, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 7

Moving on to step 2:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 6 after subtracting 14 from 20.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 7

Going ahead to step 3:
66 divided by 7 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 3 after subtracting 63 from 66.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 7

Moving on to step 4:
When dividing 33 by 7, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 1294.0
If we subtract 28 from 33, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Going ahead to step 5:
7 goes into 56 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 12948.0
Subtracting 56 from 56 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 7

Going ahead to step 6:
7 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 129480.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 7

On to step 7:
The number 7 fits into 43 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 1294806.0
The remainder is 1 after subtracting 42 from 43.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 7

Let's proceed to step 8:
7 can be fit into 13 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 12948061.0
The remainder is 6 after subtracting 7 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 12948061.8
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12948061.85
If we take 35 away from 40, 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.

On to step 11:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 12948061.857
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.

Advancing to step 12:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 12948061.8571
If we take 7 away from 10, we end up 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.

Advancing to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 12948061.85714
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.

Let's proceed to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 12948061.857142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 15:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 12948061.8571428
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 16:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12948061.85714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 12948061.85714285 with a remainder of 5e-09.
