Let's divide 421343 by 7
We're looking to find how many times 7 goes into 421343.

Moving on to step 1:
7 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 7

Step 2:
The number 7 fits into 42 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 42 from 42, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 7

Going ahead to step 3:
1 divided by 7 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 7

Going ahead to step 4:
13 divided by 7 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 601.0
Subtract 7 from 13 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 7

Advancing to step 5:
64 divided by 7 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 6019.0
Deduct 63 from 64 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 7

Moving on to step 6:
The number 7 fits into 13 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 60191.0
Deduct 7 from 13 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.

On to step 7:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 60191.8
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.

Let's proceed to step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 60191.85
If we subtract 35 from 40, we 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.

Advancing to step 9:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 60191.857
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.

Step 10:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 60191.8571
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.

Going ahead to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 60191.85714
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.

Step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 60191.857142
If we subtract 14 from 20, we get 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 13:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 60191.8571428
If we subtract 56 from 60, we 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 14:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 60191.85714285
If we take 35 away from 40, we end up 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.

The final outcome is 60191.85714285, with a leftover of 5e-09.
