We look at the division of 7073950 by 400 
We want to divide 7073950 by 400.

On to step 1:
If we divide 7 by 400, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 400

Going ahead to step 2:
70 divided by 400 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 400

On to step 3:
400 goes into 707 1 times with a remainder of 307.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 400 from 707 and we're left with 307.
Fetch the next digit (3) from the dividend, attach it to 307 and continue: 3073 / 400

On to step 4:
When dividing 3073 by 400, we get 7 with a remainder of 273.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 2800 from 3073 to get 273.
Fetch the next digit (9) from the dividend, attach it to 273 and continue: 2739 / 400

Step 5:
400 can be fit into 2739 6 times, resulting in a remainder of 339.
The next digit of our result is 6. 
Result so far: 176.0
Subtracting 2400 from 2739 leaves us with 339.
Fetch the next digit (5) from the dividend, attach it to 339 and continue: 3395 / 400

Let's proceed to step 6:
If we divide 3395 by 400, we get 8 and a remainder of 195.
Record the quotient 8 as the next digit in the result. 
Result so far: 1768.0
The remainder is 195 after subtracting 3200 from 3395.
Append the next digit (0) from the dividend to 195 and continue with: 1950 / 400

Moving on to step 7:
1950 divided by 400 is 4 with a remainder of 350.
Write down 4 as next digit of the result. 
Result so far: 17684.0
If we subtract 1600 from 1950, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 8:
When dividing 3500 by 400, we get 8 with a remainder of 300.
Put 8 as the next digit of the answer. 
Result so far: 17684.8
If we subtract 3200 from 3500, we 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.

Let's proceed to step 9:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 17684.87
Deduct 2800 from 3000 and we're left 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 10:
If we divide 2000 by 400, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17684.875
Subtract 2000 from 2000 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.

On to step 11:
If we divide 0 by 400, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17684.875
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 12:
When dividing 0 by 400, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17684.875
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 17684.875 with a remainder of 0.0.
