798840 ÷ 57 
We're looking to find how many times 57 goes into 798840.

Step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 57

Step 2:
79 divided by 57 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 79 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 57

On to step 3:
The number 57 fits into 228 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 228 away from 228, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 57

Step 4:
57 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 57

Moving on to step 5:
57 goes into 84 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1401.0
Subtract 57 from 84 to get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 57

Moving on to step 6:
270 divided by 57 is 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 14014.0
Subtract 228 from 270 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
The number 57 fits into 420 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 14014.7
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
The number 57 fits into 210 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 14014.73
If we take 171 away from 210, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
57 goes into 390 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 14014.736
Deduct 342 from 390 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
57 goes into 480 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 14014.7368
Deduct 456 from 480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
When dividing 240 by 57, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 14014.73684
If we subtract 228 from 240, we 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 12:
120 divided by 57 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 14014.736842
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 57 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 14014.7368421
If we take 57 away from 60, 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.

Step 14:
When dividing 30 by 57, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 14014.7368421
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 14014.7368421, with a leftover of 3e-08.
