We look at the division of 5100188 by 400 
Our goal is to divide 5100188 by 400.

Moving on to step 1:
400 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
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 400

Advancing to step 2:
The number 400 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 400

Step 3:
When dividing 510 by 400, we get 1 with a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 400 away from 510, we end up with 110.
Bring next digit (0) of the dividend behind the 110 and repeat the process: 1100 / 400

Going ahead to step 4:
When dividing 1100 by 400, we get 2 with a remainder of 300.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 800 from 1100 to get 300.
Append the next digit (1) from the dividend to 300 and continue with: 3001 / 400

Moving on to step 5:
If we divide 3001 by 400, we get 7 and a remainder of 201.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtract 2800 from 3001 to get 201.
Grab the next digit (8) from the dividend, add it to 201, then carry on: 2018 / 400

Let's proceed to step 6:
2018 divided by 400 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 1275.0
Subtract 2000 from 2018 to get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 400

Advancing to step 7:
If we divide 188 by 400, we get 0 and a remainder of 188.
The next digit of our result is 0. 
Result so far: 12750.0
If we subtract 0 from 188, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 8:
1880 divided by 400 is 4 with a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 12750.4
Deduct 1600 from 1880 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 9:
2800 divided by 400 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 12750.47
Deduct 2800 from 2800 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12750.47
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 400 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12750.47
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 12750.47 with a remainder of 0.0.
