45145092 ÷ 398 
We're looking to find how many times 398 goes into 45145092.

Going ahead to step 1:
If we divide 4 by 398, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 398

Going ahead to step 2:
398 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 398

Let's proceed to step 3:
If we divide 451 by 398, we get 1 and a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 398 from 451 to get 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 398

On to step 4:
534 divided by 398 is 1 with a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 398 from 534 to get 136.
Fetch the next digit (5) from the dividend, attach it to 136 and continue: 1365 / 398

On to step 5:
The number 398 fits into 1365 3 times, leaving a remainder of 171.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtract 1194 from 1365 to get 171.
Grab the next digit (0) from the dividend, add it to 171, then carry on: 1710 / 398

Step 6:
1710 divided by 398 is 4 with a remainder of 118.
The next digit of our result is 4. 
Result so far: 1134.0
Subtract 1592 from 1710 to get 118.
Fetch the next digit (9) from the dividend, attach it to 118 and continue: 1189 / 398

Going ahead to step 7:
398 goes into 1189 2 times with a remainder of 393.
Write down 2 as next digit of the result. 
Result so far: 11342.0
Subtract 796 from 1189 to get 393.
Fetch the next digit (2) from the dividend, attach it to 393 and continue: 3932 / 398

Going ahead to step 8:
398 can be fit into 3932 9 times, resulting in a remainder of 350.
Use 9 as the next digit of our solution. 
Result so far: 113429.0
The remainder is 350 after subtracting 3582 from 3932.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 9:
398 goes into 3500 8 times with a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 113429.8
Deduct 3184 from 3500 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 10:
398 goes into 3160 7 times with a remainder of 374.
The next digit of our result is 7. 
Result so far: 113429.87
Deduct 2786 from 3160 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 11:
398 can be fit into 3740 9 times, resulting in a remainder of 158.
Record the quotient 9 as the next digit in the result. 
Result so far: 113429.879
If we subtract 3582 from 3740, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 12:
The number 398 fits into 1580 3 times, leaving a remainder of 386.
Use 3 as the next digit of our solution. 
Result so far: 113429.8793
Subtract 1194 from 1580 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 13:
398 goes into 3860 9 times with a remainder of 278.
The number 9 becomes the next digit in our result. 
Result so far: 113429.87939
Subtract 3582 from 3860 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 14:
The number 398 fits into 2780 6 times, leaving a remainder of 392.
Write down 6 as next digit of the result. 
Result so far: 113429.879396
Subtract 2388 from 2780 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 15:
398 goes into 3920 9 times with a remainder of 338.
Record the quotient 9 as the next digit in the result. 
Result so far: 113429.8793969
If we subtract 3582 from 3920, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 16:
3380 divided by 398 is 8 with a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 113429.87939698
If we take 3184 away from 3380, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 113429.87939698 and a remainder of 1.96e-07.
