We look at the division of 661972 by 7 
We want to figure out the number of times 661972 can be divided by 7.

Advancing to step 1:
The number 7 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 7

Let's proceed to step 2:
7 goes into 66 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 63 from 66, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 7

Going ahead to step 3:
7 can be fit into 31 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we subtract 28 from 31, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 7

Advancing to step 4:
39 divided by 7 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 945.0
Subtracting 35 from 39 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

Going ahead to step 5:
7 goes into 47 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 9456.0
The remainder is 5 after subtracting 42 from 47.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 7

Moving on to step 6:
If we divide 52 by 7, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 94567.0
If we take 49 away from 52, 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.

Step 7:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 94567.4
If we subtract 28 from 30, 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.

Moving on to step 8:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 94567.42
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.

Let's proceed to step 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 94567.428
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.

Step 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 94567.4285
Subtract 35 from 40 to get 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.
Use 7 as the next digit of our solution. 
Result so far: 94567.42857
Subtract 49 from 50 to 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:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 94567.428571
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.

Step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 94567.4285714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 94567.42857142
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.

The quotient of the division is 94567.42857142, and the remainder is 6e-09.
