We look at the division of 71380454 by 398 
We're looking to find how many times 398 goes into 71380454.

Let's proceed to step 1:
398 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 398

Moving on to step 2:
71 divided by 398 is 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 398

Let's proceed to step 3:
The number 398 fits into 713 1 times, leaving a remainder of 315.
The next digit of our result is 1. 
Result so far: 1.0
If we take 398 away from 713, we end up with 315.
Grab the next digit (8) from the dividend, add it to 315, then carry on: 3158 / 398

Let's proceed to step 4:
The number 398 fits into 3158 7 times, leaving a remainder of 372.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 2786 from 3158, we get 372.
Fetch the next digit (0) from the dividend, attach it to 372 and continue: 3720 / 398

Advancing to step 5:
398 goes into 3720 9 times with a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 179.0
Subtract 3582 from 3720 to get 138.
Append the next digit (4) from the dividend to 138 and continue with: 1384 / 398

Advancing to step 6:
If we divide 1384 by 398, we get 3 and a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 1793.0
Deduct 1194 from 1384 and we're left with 190.
Take the next digit (5) from the dividend and append it to 190, then repeat: 1905 / 398

Step 7:
398 goes into 1905 4 times with a remainder of 313.
Use 4 as the next digit of our solution. 
Result so far: 17934.0
Subtracting 1592 from 1905 leaves us with 313.
Bring next digit (4) of the dividend behind the 313 and repeat the process: 3134 / 398

Moving on to step 8:
When dividing 3134 by 398, we get 7 with a remainder of 348.
The next digit of our result is 7. 
Result so far: 179347.0
If we subtract 2786 from 3134, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 9:
The number 398 fits into 3480 8 times, leaving a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 179347.8
If we subtract 3184 from 3480, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
If we divide 2960 by 398, we get 7 and a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 179347.87
Subtract 2786 from 2960 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 11:
When dividing 1740 by 398, we get 4 with a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 179347.874
Subtract 1592 from 1740 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
When dividing 1480 by 398, we get 3 with a remainder of 286.
The number 3 becomes the next digit in our result. 
Result so far: 179347.8743
The remainder is 286 after subtracting 1194 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 13:
When dividing 2860 by 398, we get 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 179347.87437
If we subtract 2786 from 2860, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
398 goes into 740 1 times with a remainder of 342.
The next digit of our result is 1. 
Result so far: 179347.874371
If we subtract 398 from 740, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 15:
The number 398 fits into 3420 8 times, leaving a remainder of 236.
The next digit of our result is 8. 
Result so far: 179347.8743718
The remainder is 236 after subtracting 3184 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 16:
398 can be fit into 2360 5 times, resulting in a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 179347.87437185
If we take 1990 away from 2360, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final result is 179347.87437185 with a remainder of 3.7e-07.
