Let's divide 86493883 by 400
Our goal is to divide 86493883 by 400.

Let's proceed to step 1:
400 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 400

Step 2:
When dividing 86 by 400, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 400

Moving on to step 3:
864 divided by 400 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 800 from 864 to get 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 400

Let's proceed to step 4:
When dividing 649 by 400, we get 1 with a remainder of 249.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 400 from 649 and we're left with 249.
Fetch the next digit (3) from the dividend, attach it to 249 and continue: 2493 / 400

Step 5:
400 can be fit into 2493 6 times, resulting in a remainder of 93.
Write down 6 as next digit of the result. 
Result so far: 216.0
Subtract 2400 from 2493 to get 93.
Grab the next digit (8) from the dividend, add it to 93, then carry on: 938 / 400

Advancing to step 6:
The number 400 fits into 938 2 times, leaving a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 2162.0
The remainder is 138 after subtracting 800 from 938.
Take the next digit (8) from the dividend and append it to 138, then repeat: 1388 / 400

Moving on to step 7:
400 goes into 1388 3 times with a remainder of 188.
Record the quotient 3 as the next digit in the result. 
Result so far: 21623.0
If we take 1200 away from 1388, we end up with 188.
Bring next digit (3) of the dividend behind the 188 and repeat the process: 1883 / 400

Step 8:
1883 divided by 400 is 4 with a remainder of 283.
Write down 4 as next digit of the result. 
Result so far: 216234.0
Subtract 1600 from 1883 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 9:
When dividing 2830 by 400, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 216234.7
Deduct 2800 from 2830 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
400 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 216234.7
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 216234.707
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.

Advancing to step 12:
When dividing 2000 by 400, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 216234.7075
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.

Step 13:
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: 216234.7075
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.

On to step 14:
When dividing 0 by 400, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 216234.7075
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.

Our division results in 216234.7075 with a remaining 0.0.
