We're dividing 69839521 by 400 
Let's see how many times 400 fits into 69839521.

Moving on to step 1:
If we divide 6 by 400, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 400

On to step 2:
If we divide 69 by 400, we get 0 and a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 400

Moving on to step 3:
400 can be fit into 698 1 times, resulting in a remainder of 298.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 400 from 698, we get 298.
Grab the next digit (3) from the dividend, add it to 298, then carry on: 2983 / 400

Going ahead to step 4:
The number 400 fits into 2983 7 times, leaving a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 2800 away from 2983, we end up with 183.
Include the next digit (9) from the dividend after 183, then repeat: 1839 / 400

Advancing to step 5:
400 goes into 1839 4 times with a remainder of 239.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we subtract 1600 from 1839, we get 239.
Fetch the next digit (5) from the dividend, attach it to 239 and continue: 2395 / 400

On to step 6:
2395 divided by 400 is 5 with a remainder of 395.
The next digit of our result is 5. 
Result so far: 1745.0
The remainder is 395 after subtracting 2000 from 2395.
Append the next digit (2) from the dividend to 395 and continue with: 3952 / 400

Let's proceed to step 7:
400 goes into 3952 9 times with a remainder of 352.
Use 9 as the next digit of our solution. 
Result so far: 17459.0
If we subtract 3600 from 3952, we get 352.
Grab the next digit (1) from the dividend, add it to 352, then carry on: 3521 / 400

Moving on to step 8:
When dividing 3521 by 400, we get 8 with a remainder of 321.
Write down 8 as next digit of the result. 
Result so far: 174598.0
Subtracting 3200 from 3521 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 9:
When dividing 3210 by 400, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 174598.8
Subtracting 3200 from 3210 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
400 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 174598.8
Subtract 0 from 100 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.

On to step 11:
400 goes into 1000 2 times with a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 174598.802
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.

Let's proceed to step 12:
2000 divided by 400 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 174598.8025
If we take 2000 away from 2000, 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.

On to step 13:
0 divided by 400 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 174598.8025
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:
400 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 174598.8025
Subtracting 0 from 0 leaves us 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 outcome is 174598.8025, with a leftover of 0.0.
