We look at the division of 51252438 by 980 
Let's see how many times 980 fits into 51252438.

On to step 1:
980 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 980

On to step 2:
If we divide 51 by 980, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 980

On to step 3:
980 can be fit into 512 0 times, resulting in a remainder of 512.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 512 after subtracting 0 from 512.
Grab the next digit (5) from the dividend, add it to 512, then carry on: 5125 / 980

Step 4:
If we divide 5125 by 980, we get 5 and a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4900 from 5125 to get 225.
Append the next digit (2) from the dividend to 225 and continue with: 2252 / 980

Let's proceed to step 5:
980 goes into 2252 2 times with a remainder of 292.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we take 1960 away from 2252, we end up with 292.
Grab the next digit (4) from the dividend, add it to 292, then carry on: 2924 / 980

Advancing to step 6:
If we divide 2924 by 980, we get 2 and a remainder of 964.
Put 2 as the next digit of the answer. 
Result so far: 522.0
If we subtract 1960 from 2924, we get 964.
Append the next digit (3) from the dividend to 964 and continue with: 9643 / 980

Advancing to step 7:
9643 divided by 980 is 9 with a remainder of 823.
Record the quotient 9 as the next digit in the result. 
Result so far: 5229.0
Subtract 8820 from 9643 to get 823.
Include the next digit (8) from the dividend after 823, then repeat: 8238 / 980

Step 8:
980 goes into 8238 8 times with a remainder of 398.
The next digit of our result is 8. 
Result so far: 52298.0
Subtract 7840 from 8238 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 9:
When dividing 3980 by 980, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 52298.4
Deduct 3920 from 3980 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
980 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 52298.4
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 11:
When dividing 6000 by 980, we get 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 52298.406
If we take 5880 away from 6000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
980 can be fit into 1200 1 times, resulting in a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 52298.4061
If we take 980 away from 1200, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 13:
980 can be fit into 2200 2 times, resulting in a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 52298.40612
If we subtract 1960 from 2200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 14:
When dividing 2400 by 980, we get 2 with a remainder of 440.
The number 2 becomes the next digit in our result. 
Result so far: 52298.406122
The remainder is 440 after subtracting 1960 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 52298.406122 with a remaining 4.4e-05.
