We look at the division of 29603543 by 400 
We want to figure out the number of times 29603543 can be divided by 400.

Step 1:
400 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 400

On to step 2:
If we divide 29 by 400, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 400

Moving on to step 3:
400 goes into 296 0 times with a remainder of 296.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 296 to get 296.
Take the next digit (0) from the dividend and append it to 296, then repeat: 2960 / 400

Step 4:
The number 400 fits into 2960 7 times, leaving a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 2800 away from 2960, we end up with 160.
Take the next digit (3) from the dividend and append it to 160, then repeat: 1603 / 400

Step 5:
When dividing 1603 by 400, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we subtract 1600 from 1603, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 400

Going ahead to step 6:
400 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 740.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 400

On to step 7:
400 goes into 354 0 times with a remainder of 354.
Use 0 as the next digit of our solution. 
Result so far: 7400.0
Subtracting 0 from 354 leaves us with 354.
Append the next digit (3) from the dividend to 354 and continue with: 3543 / 400

Going ahead to step 8:
400 can be fit into 3543 8 times, resulting in a remainder of 343.
Use 8 as the next digit of our solution. 
Result so far: 74008.0
The remainder is 343 after subtracting 3200 from 3543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 9:
If we divide 3430 by 400, we get 8 and a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 74008.8
Subtract 3200 from 3430 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
The number 400 fits into 2300 5 times, leaving a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 74008.85
Deduct 2000 from 2300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
Put 7 as the next digit of the answer. 
Result so far: 74008.857
If we take 2800 away from 3000, 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.

Advancing to step 12:
400 goes into 2000 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 74008.8575
Deduct 2000 from 2000 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.

Advancing to step 13:
When dividing 0 by 400, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 74008.8575
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.

Let's proceed 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: 74008.8575
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.

After the division, we end up with 74008.8575 and a remainder of 0.0.
