57046669 ÷ 398 
Our goal is to divide 57046669 by 398.

On to step 1:
398 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 398

Let's proceed to step 2:
When dividing 57 by 398, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 398

Let's proceed to step 3:
If we divide 570 by 398, we get 1 and a remainder of 172.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 172 after subtracting 398 from 570.
Bring next digit (4) of the dividend behind the 172 and repeat the process: 1724 / 398

On to step 4:
When dividing 1724 by 398, we get 4 with a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1592 from 1724 leaves us with 132.
Bring next digit (6) of the dividend behind the 132 and repeat the process: 1326 / 398

Advancing to step 5:
398 goes into 1326 3 times with a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we take 1194 away from 1326, we end up with 132.
Grab the next digit (6) from the dividend, add it to 132, then carry on: 1326 / 398

Let's proceed to step 6:
1326 divided by 398 is 3 with a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 1433.0
The remainder is 132 after subtracting 1194 from 1326.
Include the next digit (6) from the dividend after 132, then repeat: 1326 / 398

Step 7:
398 goes into 1326 3 times with a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 14333.0
Subtracting 1194 from 1326 leaves us with 132.
Include the next digit (9) from the dividend after 132, then repeat: 1329 / 398

Moving on to step 8:
The number 398 fits into 1329 3 times, leaving a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 143333.0
Subtracting 1194 from 1329 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
When dividing 1350 by 398, we get 3 with a remainder of 156.
Put 3 as the next digit of the answer. 
Result so far: 143333.3
If we take 1194 away from 1350, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 10:
398 goes into 1560 3 times with a remainder of 366.
Use 3 as the next digit of our solution. 
Result so far: 143333.33
If we subtract 1194 from 1560, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

In conclusion, the division gives 143333.33 with a balance of 0.366.
