991573 ÷ 7 
Our goal is to divide 991573 by 7.

Let's proceed to step 1:
When dividing 9 by 7, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 7 from 9, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Moving on to step 2:
The number 7 fits into 29 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 28 from 29 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 7

Advancing to step 3:
11 divided by 7 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
The remainder is 4 after subtracting 7 from 11.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 7

Let's proceed to step 4:
When dividing 45 by 7, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1416.0
If we subtract 42 from 45, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 7

On to step 5:
If we divide 37 by 7, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 14165.0
If we subtract 35 from 37, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 7

Let's proceed to step 6:
7 can be fit into 23 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 141653.0
If we subtract 21 from 23, we 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.

Going ahead to step 7:
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: 141653.2
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.

Advancing to step 8:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 141653.28
Subtracting 56 from 60 leaves us 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.

Advancing to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 141653.285
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.

Moving on to step 10:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 141653.2857
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.

Moving on to step 11:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 141653.28571
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.

Step 12:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 141653.285714
The remainder is 2 after subtracting 28 from 30.
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 13:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 141653.2857142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 141653.28571428
Subtracting 56 from 60 leaves us 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.

The quotient of the division is 141653.28571428, and the remainder is 4e-09.
