400211 ÷ 78 
Let's see how many times 78 fits into 400211.

Advancing to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 78

Going ahead to step 2:
If we divide 40 by 78, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 78

Moving on to step 3:
78 goes into 400 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 390 from 400 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 78

Advancing to step 4:
When dividing 102 by 78, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 78 from 102 leaves us with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 78

Advancing to step 5:
If we divide 241 by 78, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 513.0
Subtract 234 from 241 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 78

Advancing to step 6:
The number 78 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 5130.0
Subtract 0 from 71 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
If we divide 710 by 78, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 5130.9
Deduct 702 from 710 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 5130.91
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 78, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5130.91
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 78 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 5130.9102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5130.91025
Deduct 390 from 440 and we're left with 50.
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 12:
78 goes into 500 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 5130.910256
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
If we divide 320 by 78, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 5130.9102564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
If we divide 80 by 78, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 5130.91025641
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 5130.91025641, with a leftover of 2e-09.
