We divide 30979085 by 400
We want to figure out the number of times 30979085 can be divided by 400.

Step 1:
The number 400 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 400

Moving on to step 2:
30 divided by 400 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 400

Step 3:
400 can be fit into 309 0 times, resulting in a remainder of 309.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 309, we end up with 309.
Include the next digit (7) from the dividend after 309, then repeat: 3097 / 400

Let's proceed to step 4:
400 can be fit into 3097 7 times, resulting in a remainder of 297.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 297 after subtracting 2800 from 3097.
Fetch the next digit (9) from the dividend, attach it to 297 and continue: 2979 / 400

Moving on to step 5:
The number 400 fits into 2979 7 times, leaving a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Deduct 2800 from 2979 and we're left with 179.
Take the next digit (0) from the dividend and append it to 179, then repeat: 1790 / 400

Let's proceed to step 6:
400 goes into 1790 4 times with a remainder of 190.
Record the quotient 4 as the next digit in the result. 
Result so far: 774.0
Subtract 1600 from 1790 to get 190.
Grab the next digit (8) from the dividend, add it to 190, then carry on: 1908 / 400

Advancing to step 7:
400 can be fit into 1908 4 times, resulting in a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 7744.0
Subtract 1600 from 1908 to get 308.
Grab the next digit (5) from the dividend, add it to 308, then carry on: 3085 / 400

Going ahead to step 8:
400 goes into 3085 7 times with a remainder of 285.
The next digit of our result is 7. 
Result so far: 77447.0
Subtract 2800 from 3085 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 9:
400 can be fit into 2850 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 77447.7
The remainder is 50 after subtracting 2800 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 400, we get 1 and a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 77447.71
If we subtract 400 from 500, we 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.

Moving on to step 11:
400 goes into 1000 2 times with a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 77447.712
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.

Let's proceed to step 12:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 77447.7125
Subtracting 2000 from 2000 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.

Step 13:
400 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 77447.7125
Subtract 0 from 0 to 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.

Going ahead to step 14:
0 divided by 400 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 77447.7125
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.

The final outcome is 77447.7125, with a leftover of 0.0.
