We look at the division of 34315372 by 406 
We want to divide 34315372 by 406.

Step 1:
406 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 406

Step 2:
34 divided by 406 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 406

Step 3:
The number 406 fits into 343 0 times, leaving a remainder of 343.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 343 to get 343.
Bring next digit (1) of the dividend behind the 343 and repeat the process: 3431 / 406

Advancing to step 4:
If we divide 3431 by 406, we get 8 and a remainder of 183.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 3248 from 3431 leaves us with 183.
Take the next digit (5) from the dividend and append it to 183, then repeat: 1835 / 406

Going ahead to step 5:
If we divide 1835 by 406, we get 4 and a remainder of 211.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 1624 away from 1835, we end up with 211.
Take the next digit (3) from the dividend and append it to 211, then repeat: 2113 / 406

On to step 6:
If we divide 2113 by 406, we get 5 and a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 845.0
Subtracting 2030 from 2113 leaves us with 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 406

On to step 7:
406 goes into 837 2 times with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 8452.0
If we take 812 away from 837, we end up with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 406

On to step 8:
The number 406 fits into 252 0 times, leaving a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 84520.0
If we subtract 0 from 252, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 9:
If we divide 2520 by 406, we get 6 and a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 84520.6
The remainder is 84 after subtracting 2436 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
The number 406 fits into 840 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 84520.62
The remainder is 28 after subtracting 812 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
If we divide 280 by 406, we get 0 and a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 84520.62
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
406 can be fit into 2800 6 times, resulting in a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 84520.6206
Subtracting 2436 from 2800 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 13:
If we divide 3640 by 406, we get 8 and a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 84520.62068
The remainder is 392 after subtracting 3248 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 14:
406 can be fit into 3920 9 times, resulting in a remainder of 266.
Use 9 as the next digit of our solution. 
Result so far: 84520.620689
Subtracting 3654 from 3920 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 15:
2660 divided by 406 is 6 with a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 84520.6206896
Deduct 2436 from 2660 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 16:
The number 406 fits into 2240 5 times, leaving a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 84520.62068965
Subtracting 2030 from 2240 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 84520.62068965, with a leftover of 2.1e-07.
