Let's divide 420301 by 57
We want to divide 420301 by 57.

Step 1:
When dividing 4 by 57, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 57

Let's proceed to step 2:
57 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 57

On to step 3:
57 goes into 420 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 399 from 420 leaves us with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 57

Going ahead to step 4:
The number 57 fits into 213 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we take 171 away from 213, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 57

Advancing to step 5:
57 can be fit into 420 7 times, resulting in a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 737.0
If we take 399 away from 420, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 57

On to step 6:
If we divide 211 by 57, we get 3 and a remainder of 40.
The next digit of our result is 3. 
Result so far: 7373.0
If we subtract 171 from 211, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 57, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7373.7
If we take 399 away from 400, 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.

Moving on to step 8:
57 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7373.7
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
57 can be fit into 100 1 times, resulting in a remainder of 43.
The next digit of our result is 1. 
Result so far: 7373.701
If we subtract 57 from 100, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
When dividing 430 by 57, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7373.7017
The remainder is 31 after subtracting 399 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
If we divide 310 by 57, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7373.70175
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
250 divided by 57 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 7373.701754
Deduct 228 from 250 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
When dividing 220 by 57, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 7373.7017543
The remainder is 49 after subtracting 171 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
When dividing 490 by 57, we get 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 7373.70175438
The remainder is 34 after subtracting 456 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 7373.70175438, with a leftover of 3.4e-08.
