75237419 ÷ 398 
We want to divide 75237419 by 398.

Step 1:
If we divide 7 by 398, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 398

Moving on to step 2:
If we divide 75 by 398, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 398

Moving on to step 3:
When dividing 752 by 398, we get 1 with a remainder of 354.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 398 from 752 leaves us with 354.
Append the next digit (3) from the dividend to 354 and continue with: 3543 / 398

Let's proceed to step 4:
398 goes into 3543 8 times with a remainder of 359.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 359 after subtracting 3184 from 3543.
Append the next digit (7) from the dividend to 359 and continue with: 3597 / 398

Moving on to step 5:
398 can be fit into 3597 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 189.0
If we take 3582 away from 3597, we end up with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 398

Advancing to step 6:
154 divided by 398 is 0 with a remainder of 154.
The next digit of our result is 0. 
Result so far: 1890.0
Subtracting 0 from 154 leaves us with 154.
Fetch the next digit (1) from the dividend, attach it to 154 and continue: 1541 / 398

Step 7:
1541 divided by 398 is 3 with a remainder of 347.
Use 3 as the next digit of our solution. 
Result so far: 18903.0
If we take 1194 away from 1541, we end up with 347.
Include the next digit (9) from the dividend after 347, then repeat: 3479 / 398

Let's proceed to step 8:
When dividing 3479 by 398, we get 8 with a remainder of 295.
The number 8 becomes the next digit in our result. 
Result so far: 189038.0
If we take 3184 away from 3479, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 9:
If we divide 2950 by 398, we get 7 and a remainder of 164.
Record the quotient 7 as the next digit in the result. 
Result so far: 189038.7
Subtract 2786 from 2950 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
If we divide 1640 by 398, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 189038.74
Deduct 1592 from 1640 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
If we divide 480 by 398, we get 1 and a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 189038.741
Subtracting 398 from 480 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 12:
If we divide 820 by 398, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 189038.7412
If we subtract 796 from 820, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
398 can be fit into 240 0 times, resulting in a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 189038.7412
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
The number 398 fits into 2400 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 189038.741206
If we take 2388 away from 2400, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 15:
The number 398 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 189038.741206
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
The number 398 fits into 1200 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 189038.74120603
Subtract 1194 from 1200 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 189038.74120603 with a remainder of 6e-09.
