We divide 73798609 by 400
We want to figure out the number of times 73798609 can be divided by 400.

Step 1:
The number 400 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 400

Moving on to step 2:
73 divided by 400 is 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (7) from the dividend and append it to 73, then repeat: 737 / 400

Advancing to step 3:
737 divided by 400 is 1 with a remainder of 337.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 400 from 737 to get 337.
Fetch the next digit (9) from the dividend, attach it to 337 and continue: 3379 / 400

Going ahead to step 4:
400 goes into 3379 8 times with a remainder of 179.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 179 after subtracting 3200 from 3379.
Bring next digit (8) of the dividend behind the 179 and repeat the process: 1798 / 400

Step 5:
If we divide 1798 by 400, we get 4 and a remainder of 198.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Subtract 1600 from 1798 to get 198.
Include the next digit (6) from the dividend after 198, then repeat: 1986 / 400

On to step 6:
1986 divided by 400 is 4 with a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 1844.0
The remainder is 386 after subtracting 1600 from 1986.
Fetch the next digit (0) from the dividend, attach it to 386 and continue: 3860 / 400

Let's proceed to step 7:
400 can be fit into 3860 9 times, resulting in a remainder of 260.
Put 9 as the next digit of the answer. 
Result so far: 18449.0
Subtracting 3600 from 3860 leaves us with 260.
Include the next digit (9) from the dividend after 260, then repeat: 2609 / 400

Going ahead to step 8:
400 can be fit into 2609 6 times, resulting in a remainder of 209.
The number 6 becomes the next digit in our result. 
Result so far: 184496.0
Deduct 2400 from 2609 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
When dividing 2090 by 400, we get 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 184496.5
Deduct 2000 from 2090 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
400 goes into 900 2 times with a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 184496.52
Deduct 800 from 900 and we're left 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.

Advancing to step 11:
400 goes into 1000 2 times with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 184496.522
The remainder is 200 after subtracting 800 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 184496.522, and the remainder is 0.02.
