16146398 ÷ 351 
We want to figure out the number of times 16146398 can be divided by 351.

Going ahead to step 1:
1 divided by 351 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 351

Step 2:
16 divided by 351 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 351

Let's proceed to step 3:
351 can be fit into 161 0 times, resulting in a remainder of 161.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 161 leaves us with 161.
Bring next digit (4) of the dividend behind the 161 and repeat the process: 1614 / 351

Step 4:
1614 divided by 351 is 4 with a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 210 after subtracting 1404 from 1614.
Take the next digit (6) from the dividend and append it to 210, then repeat: 2106 / 351

Let's proceed to step 5:
351 can be fit into 2106 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtract 2106 from 2106 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 351

Step 6:
When dividing 3 by 351, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 460.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 351

On to step 7:
351 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 4600.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 351

Moving on to step 8:
When dividing 398 by 351, we get 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 46001.0
Subtracting 351 from 398 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
470 divided by 351 is 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 46001.1
Deduct 351 from 470 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 10:
If we divide 1190 by 351, we get 3 and a remainder of 137.
The next digit of our result is 3. 
Result so far: 46001.13
If we subtract 1053 from 1190, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 11:
351 can be fit into 1370 3 times, resulting in a remainder of 317.
Put 3 as the next digit of the answer. 
Result so far: 46001.133
Deduct 1053 from 1370 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final outcome is 46001.133, with a leftover of 0.0317.
