422378 ÷ 7 
We're looking to find how many times 7 goes into 422378.

Advancing to step 1:
4 divided by 7 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 7

Step 2:
If we divide 42 by 7, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 0 after subtracting 42 from 42.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 7

On to step 3:
The number 7 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 7

Step 4:
If we divide 23 by 7, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 603.0
Subtract 21 from 23 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 7

Advancing to step 5:
27 divided by 7 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 6033.0
Subtract 21 from 27 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 7

Going ahead to step 6:
When dividing 68 by 7, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 60339.0
Deduct 63 from 68 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.

Moving on to step 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 60339.7
Deduct 49 from 50 and we're left 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.

Moving on to step 8:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 60339.71
Subtracting 7 from 10 leaves us 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 9:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 60339.714
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.

Let's proceed to step 10:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 60339.7142
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.

Advancing to step 11:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 60339.71428
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.

Step 12:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 60339.714285
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.

Going ahead to step 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 60339.7142857
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.

Going ahead to step 14:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 60339.71428571
Subtracting 7 from 10 leaves us 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.

In conclusion, the division gives 60339.71428571 with a balance of 3e-09.
