Let's divide 139598 by 57
Our goal is to divide 139598 by 57.

Advancing to step 1:
1 divided by 57 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 57

Advancing to step 2:
The number 57 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 57

On to step 3:
When dividing 139 by 57, we get 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 114 away from 139, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 57

On to step 4:
57 can be fit into 255 4 times, resulting in a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 228 away from 255, we end up with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 57

Step 5:
279 divided by 57 is 4 with a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
If we subtract 228 from 279, we get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 57

Step 6:
57 can be fit into 518 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 2449.0
If we subtract 513 from 518, 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.

Moving on to step 7:
57 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 2449.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
57 can be fit into 500 8 times, resulting in a remainder of 44.
The next digit of our result is 8. 
Result so far: 2449.08
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
The number 57 fits into 440 7 times, leaving a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 2449.087
Subtracting 399 from 440 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
If we divide 410 by 57, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 2449.0877
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 2449.0877, and the remainder is 0.00011.
