Let's divide 420045 by 57
We want to figure out the number of times 420045 can be divided by 57.

Step 1:
57 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 57

Advancing to step 2:
When dividing 42 by 57, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 57

Moving on to step 3:
57 goes into 420 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 399 from 420 to get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 57

Advancing to step 4:
When dividing 210 by 57, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 171 from 210, we get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 57

Going ahead to step 5:
When dividing 394 by 57, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 736.0
If we take 342 away from 394, we end up with 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 57

Let's proceed to step 6:
57 goes into 525 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 7369.0
Subtract 513 from 525 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 57 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 7369.2
If we take 114 away from 120, we end up 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 8:
60 divided by 57 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 7369.21
The remainder is 3 after subtracting 57 from 60.
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 9:
The number 57 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7369.21
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 57, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7369.2105
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 7369.21052
If we take 114 away from 150, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
360 divided by 57 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 7369.210526
Subtract 342 from 360 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
57 can be fit into 180 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 7369.2105263
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
57 can be fit into 90 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 7369.21052631
If we take 57 away from 90, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 7369.21052631, with a leftover of 3.3e-08.
