66347261 ÷ 7 
We want to divide 66347261 by 7.

Going ahead to step 1:
7 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 7

Moving on to step 2:
66 divided by 7 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 63 from 66 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 7

Advancing to step 3:
33 divided by 7 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 28 away from 33, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 7

Going ahead to step 4:
The number 7 fits into 54 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 947.0
The remainder is 5 after subtracting 49 from 54.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 7

Let's proceed to step 5:
When dividing 57 by 7, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 9478.0
Subtracting 56 from 57 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 7

On to step 6:
12 divided by 7 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 94781.0
Subtract 7 from 12 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 7

On to step 7:
The number 7 fits into 56 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 947818.0
Subtract 56 from 56 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 7

Moving on to step 8:
7 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 9478180.0
If we take 0 away from 1, we end up 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 9:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 9478180.1
The remainder is 3 after subtracting 7 from 10.
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 10:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 9478180.14
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.

Advancing to step 11:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 9478180.142
Subtracting 14 from 20 leaves us 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.

Let's proceed to step 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 9478180.1428
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.

Step 13:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9478180.14285
Subtracting 35 from 40 leaves us 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.

Going ahead to step 14:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 9478180.142857
If we take 49 away from 50, we end up 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.

Advancing to step 15:
7 goes into 10 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 9478180.1428571
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.

Let's proceed to step 16:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9478180.14285714
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.

The final outcome is 9478180.14285714, with a leftover of 2e-09.
