Let's divide 69160021 by 400
Our goal is to divide 69160021 by 400.

Advancing to step 1:
400 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 400

Moving on to step 2:
400 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 400

Step 3:
The number 400 fits into 691 1 times, leaving a remainder of 291.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 400 from 691, we get 291.
Fetch the next digit (6) from the dividend, attach it to 291 and continue: 2916 / 400

Moving on to step 4:
400 can be fit into 2916 7 times, resulting in a remainder of 116.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 2800 from 2916, we get 116.
Include the next digit (0) from the dividend after 116, then repeat: 1160 / 400

Let's proceed to step 5:
When dividing 1160 by 400, we get 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
If we take 800 away from 1160, we end up with 360.
Include the next digit (0) from the dividend after 360, then repeat: 3600 / 400

Step 6:
The number 400 fits into 3600 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 1729.0
Deduct 3600 from 3600 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 400

Let's proceed to step 7:
2 divided by 400 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 17290.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 400

Step 8:
If we divide 21 by 400, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 172900.0
Deduct 0 from 21 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
400 can be fit into 210 0 times, resulting in a remainder of 210.
The next digit of our result is 0. 
Result so far: 172900.0
Deduct 0 from 210 and we're left 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:
When dividing 2100 by 400, we get 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 172900.05
Subtracting 2000 from 2100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
400 can be fit into 1000 2 times, resulting in a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 172900.052
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.

Let's proceed 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: 172900.0525
Subtracting 2000 from 2000 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.

Going ahead to step 13:
0 divided by 400 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 172900.0525
If we take 0 away from 0, we end up 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.

On to step 14:
400 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 172900.0525
If we take 0 away from 0, we end up 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 quotient of the division is 172900.0525, and the remainder is 0.0.
