We're dividing 53667101 by 400 
We want to divide 53667101 by 400.

Advancing to step 1:
5 divided by 400 is 0 with 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.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 400

Going ahead to step 2:
400 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 400

Moving on to step 3:
If we divide 536 by 400, we get 1 and a remainder of 136.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 400 away from 536, we end up with 136.
Grab the next digit (6) from the dividend, add it to 136, then carry on: 1366 / 400

Advancing to step 4:
1366 divided by 400 is 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 1200 from 1366 and we're left with 166.
Include the next digit (7) from the dividend after 166, then repeat: 1667 / 400

On to step 5:
400 goes into 1667 4 times with a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 67 after subtracting 1600 from 1667.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 400

Step 6:
400 can be fit into 671 1 times, resulting in a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 1341.0
Subtracting 400 from 671 leaves us with 271.
Take the next digit (0) from the dividend and append it to 271, then repeat: 2710 / 400

Let's proceed to step 7:
If we divide 2710 by 400, we get 6 and a remainder of 310.
Write down 6 as next digit of the result. 
Result so far: 13416.0
If we subtract 2400 from 2710, we get 310.
Fetch the next digit (1) from the dividend, attach it to 310 and continue: 3101 / 400

Let's proceed to step 8:
400 goes into 3101 7 times with a remainder of 301.
The next digit of our result is 7. 
Result so far: 134167.0
If we subtract 2800 from 3101, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 9:
400 goes into 3010 7 times with a remainder of 210.
The next digit of our result is 7. 
Result so far: 134167.7
Subtracting 2800 from 3010 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
The number 400 fits into 2100 5 times, leaving a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 134167.75
Subtract 2000 from 2100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
When dividing 1000 by 400, we get 2 with a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 134167.752
Subtract 800 from 1000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
If we divide 2000 by 400, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 134167.7525
The remainder is 0 after subtracting 2000 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 134167.7525
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.

Advancing to step 14:
If we divide 0 by 400, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 134167.7525
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.

The final result is 134167.7525 with a remainder of 0.0.
