121898 ÷ 57 
We want to divide 121898 by 57.

Step 1:
57 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 57

On to step 2:
When dividing 12 by 57, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 57

Advancing to step 3:
The number 57 fits into 121 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 7 after subtracting 114 from 121.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 57

On to step 4:
57 goes into 78 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 57 away from 78, we end up with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 57

On to step 5:
The number 57 fits into 219 3 times, leaving a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Deduct 171 from 219 and we're left with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 57

Advancing to step 6:
If we divide 488 by 57, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 2138.0
If we subtract 456 from 488, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
If we divide 320 by 57, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2138.5
Subtract 285 from 320 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
57 can be fit into 350 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2138.56
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 57 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 2138.561
Subtract 57 from 80 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
230 divided by 57 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 2138.5614
If we subtract 228 from 230, 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.

Moving on to step 11:
If we divide 20 by 57, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2138.5614
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
When dividing 200 by 57, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 2138.561403
The remainder is 29 after subtracting 171 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
57 goes into 290 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2138.5614035
Subtracting 285 from 290 leaves us 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.

Moving on to step 14:
If we divide 50 by 57, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 2138.5614035
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 2138.5614035 and a remainder of 5e-08.
