371642 divided by 7 
The aim is to understand the frequency of 7 in 371642.

Going ahead to step 1:
3 divided by 7 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 7

Moving on to step 2:
37 divided by 7 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 35 away from 37, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 7

On to step 3:
If we divide 21 by 7, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 21 from 21 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 7

On to step 4:
7 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 530.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Moving on to step 5:
When dividing 64 by 7, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 5309.0
Deduct 63 from 64 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 7

Let's proceed to step 6:
7 goes into 12 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 53091.0
The remainder is 5 after subtracting 7 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 53091.7
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.

Let's proceed to step 8:
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: 53091.71
Deduct 7 from 10 and we're left 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.

Moving on to step 9:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 53091.714
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.

Step 10:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 53091.7142
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 11:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 53091.71428
Subtract 56 from 60 to get 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 12:
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: 53091.714285
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.

On to step 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 53091.7142857
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.

Step 14:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 53091.71428571
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.

The quotient of the division is 53091.71428571, and the remainder is 3e-09.
