53785079 divided by 400 
We want to divide 53785079 by 400.

On to step 1:
5 divided by 400 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 400

Moving on to step 2:
400 goes into 53 0 times with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 400

Step 3:
When dividing 537 by 400, we get 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 137 after subtracting 400 from 537.
Grab the next digit (8) from the dividend, add it to 137, then carry on: 1378 / 400

Step 4:
400 goes into 1378 3 times with a remainder of 178.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 178 after subtracting 1200 from 1378.
Fetch the next digit (5) from the dividend, attach it to 178 and continue: 1785 / 400

Moving on to step 5:
1785 divided by 400 is 4 with a remainder of 185.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Deduct 1600 from 1785 and we're left with 185.
Take the next digit (0) from the dividend and append it to 185, then repeat: 1850 / 400

Step 6:
When dividing 1850 by 400, we get 4 with a remainder of 250.
Record the quotient 4 as the next digit in the result. 
Result so far: 1344.0
If we take 1600 away from 1850, we end up with 250.
Fetch the next digit (7) from the dividend, attach it to 250 and continue: 2507 / 400

Advancing to step 7:
If we divide 2507 by 400, we get 6 and a remainder of 107.
The next digit of our result is 6. 
Result so far: 13446.0
If we take 2400 away from 2507, we end up with 107.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 400

Let's proceed to step 8:
400 goes into 1079 2 times with a remainder of 279.
Write down 2 as next digit of the result. 
Result so far: 134462.0
Subtracting 800 from 1079 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 9:
400 can be fit into 2790 6 times, resulting in a remainder of 390.
Put 6 as the next digit of the answer. 
Result so far: 134462.6
Deduct 2400 from 2790 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 10:
3900 divided by 400 is 9 with a remainder of 300.
Use 9 as the next digit of our solution. 
Result so far: 134462.69
Subtracting 3600 from 3900 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
The number 400 fits into 3000 7 times, leaving a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 134462.697
If we take 2800 away from 3000, we end up with 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:
400 goes into 2000 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 134462.6975
If we subtract 2000 from 2000, we 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 13:
If we divide 0 by 400, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 134462.6975
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 14:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 134462.6975
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 134462.6975 and a remainder of 0.0.
