Let's divide 73641878 by 400
We're looking to find how many times 400 goes into 73641878.

Advancing to step 1:
400 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 400

Step 2:
When dividing 73 by 400, we get 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 400

Moving on to step 3:
If we divide 736 by 400, we get 1 and a remainder of 336.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 400 from 736, we get 336.
Grab the next digit (4) from the dividend, add it to 336, then carry on: 3364 / 400

On to step 4:
If we divide 3364 by 400, we get 8 and a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3200 from 3364 to get 164.
Include the next digit (1) from the dividend after 164, then repeat: 1641 / 400

Going ahead to step 5:
If we divide 1641 by 400, we get 4 and a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 184.0
If we subtract 1600 from 1641, we get 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 400

Going ahead to step 6:
When dividing 418 by 400, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1841.0
Deduct 400 from 418 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 400

Advancing to step 7:
187 divided by 400 is 0 with a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 18410.0
The remainder is 187 after subtracting 0 from 187.
Fetch the next digit (8) from the dividend, attach it to 187 and continue: 1878 / 400

On to step 8:
400 can be fit into 1878 4 times, resulting in a remainder of 278.
The next digit of our result is 4. 
Result so far: 184104.0
If we take 1600 away from 1878, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 9:
400 can be fit into 2780 6 times, resulting in a remainder of 380.
The next digit of our result is 6. 
Result so far: 184104.6
If we take 2400 away from 2780, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
If we divide 3800 by 400, we get 9 and a remainder of 200.
Use 9 as the next digit of our solution. 
Result so far: 184104.69
The remainder is 200 after subtracting 3600 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
If we divide 2000 by 400, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 184104.695
The remainder is 0 after subtracting 2000 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
400 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 184104.695
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.

Going ahead to step 13:
If we divide 0 by 400, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 184104.695
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.

The final result is 184104.695 with a remainder of 0.0.
