We look at the division of 84493151 by 638 
Our goal is to divide 84493151 by 638.

On to step 1:
The number 638 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 638

Step 2:
638 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 638

Let's proceed to step 3:
When dividing 844 by 638, we get 1 with a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 638 from 844 to get 206.
Append the next digit (9) from the dividend to 206 and continue with: 2069 / 638

Going ahead to step 4:
The number 638 fits into 2069 3 times, leaving a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1914 from 2069, we get 155.
Bring next digit (3) of the dividend behind the 155 and repeat the process: 1553 / 638

On to step 5:
When dividing 1553 by 638, we get 2 with a remainder of 277.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Subtracting 1276 from 1553 leaves us with 277.
Include the next digit (1) from the dividend after 277, then repeat: 2771 / 638

On to step 6:
2771 divided by 638 is 4 with a remainder of 219.
Put 4 as the next digit of the answer. 
Result so far: 1324.0
If we take 2552 away from 2771, we end up with 219.
Take the next digit (5) from the dividend and append it to 219, then repeat: 2195 / 638

Step 7:
638 can be fit into 2195 3 times, resulting in a remainder of 281.
The number 3 becomes the next digit in our result. 
Result so far: 13243.0
Subtract 1914 from 2195 to get 281.
Include the next digit (1) from the dividend after 281, then repeat: 2811 / 638

Going ahead to step 8:
If we divide 2811 by 638, we get 4 and a remainder of 259.
Record the quotient 4 as the next digit in the result. 
Result so far: 132434.0
If we take 2552 away from 2811, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
2590 divided by 638 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 132434.4
The remainder is 38 after subtracting 2552 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
638 can be fit into 380 0 times, resulting in a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 132434.4
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
The number 638 fits into 3800 5 times, leaving a remainder of 610.
Use 5 as the next digit of our solution. 
Result so far: 132434.405
Deduct 3190 from 3800 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 12:
When dividing 6100 by 638, we get 9 with a remainder of 358.
Write down 9 as next digit of the result. 
Result so far: 132434.4059
Subtracting 5742 from 6100 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 13:
If we divide 3580 by 638, we get 5 and a remainder of 390.
Write down 5 as next digit of the result. 
Result so far: 132434.40595
The remainder is 390 after subtracting 3190 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 14:
3900 divided by 638 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 132434.405956
Subtracting 3828 from 3900 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
638 goes into 720 1 times with a remainder of 82.
The next digit of our result is 1. 
Result so far: 132434.4059561
Subtract 638 from 720 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 16:
638 goes into 820 1 times with a remainder of 182.
Record the quotient 1 as the next digit in the result. 
Result so far: 132434.40595611
Subtract 638 from 820 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

In conclusion, the division gives 132434.40595611 with a balance of 1.82e-07.
