We're dividing 79120193 by 400 
We're looking to find how many times 400 goes into 79120193.

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
If we take 0 away from 7, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 400

Going ahead to step 2:
When dividing 79 by 400, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 400

Going ahead to step 3:
If we divide 791 by 400, we get 1 and a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 400 from 791 to get 391.
Append the next digit (2) from the dividend to 391 and continue with: 3912 / 400

Going ahead to step 4:
3912 divided by 400 is 9 with a remainder of 312.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 312 after subtracting 3600 from 3912.
Bring next digit (0) of the dividend behind the 312 and repeat the process: 3120 / 400

Step 5:
If we divide 3120 by 400, we get 7 and a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 197.0
If we take 2800 away from 3120, we end up with 320.
Fetch the next digit (1) from the dividend, attach it to 320 and continue: 3201 / 400

On to step 6:
When dividing 3201 by 400, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1978.0
Subtracting 3200 from 3201 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 400

Step 7:
The number 400 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 19780.0
If we subtract 0 from 19, we get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 400

Moving on to step 8:
400 goes into 193 0 times with a remainder of 193.
The next digit of our result is 0. 
Result so far: 197800.0
Subtract 0 from 193 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 9:
1930 divided by 400 is 4 with a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 197800.4
Deduct 1600 from 1930 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
400 goes into 3300 8 times with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 197800.48
Subtract 3200 from 3300 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:
1000 divided by 400 is 2 with a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 197800.482
If we take 800 away from 1000, 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:
2000 divided by 400 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 197800.4825
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:
If we divide 0 by 400, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 197800.4825
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.

Going ahead to step 14:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 197800.4825
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 quotient of the division is 197800.4825, and the remainder is 0.0.
