We look at the division of 74848861 by 638 
We want to figure out the number of times 74848861 can be divided by 638.

On to step 1:
638 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 638

Moving on to step 2:
638 can be fit into 74 0 times, resulting in a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 638

Advancing to step 3:
When dividing 748 by 638, we get 1 with a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 638 away from 748, we end up with 110.
Append the next digit (4) from the dividend to 110 and continue with: 1104 / 638

Moving on to step 4:
638 goes into 1104 1 times with a remainder of 466.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 638 from 1104 and we're left with 466.
Grab the next digit (8) from the dividend, add it to 466, then carry on: 4668 / 638

Going ahead to step 5:
The number 638 fits into 4668 7 times, leaving a remainder of 202.
Put 7 as the next digit of the answer. 
Result so far: 117.0
If we take 4466 away from 4668, we end up with 202.
Include the next digit (8) from the dividend after 202, then repeat: 2028 / 638

Going ahead to step 6:
638 goes into 2028 3 times with a remainder of 114.
Put 3 as the next digit of the answer. 
Result so far: 1173.0
Subtracting 1914 from 2028 leaves us with 114.
Take the next digit (6) from the dividend and append it to 114, then repeat: 1146 / 638

Let's proceed to step 7:
The number 638 fits into 1146 1 times, leaving a remainder of 508.
Record the quotient 1 as the next digit in the result. 
Result so far: 11731.0
Deduct 638 from 1146 and we're left with 508.
Include the next digit (1) from the dividend after 508, then repeat: 5081 / 638

Advancing to step 8:
638 goes into 5081 7 times with a remainder of 615.
Write down 7 as next digit of the result. 
Result so far: 117317.0
The remainder is 615 after subtracting 4466 from 5081.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 9:
6150 divided by 638 is 9 with a remainder of 408.
Use 9 as the next digit of our solution. 
Result so far: 117317.9
If we take 5742 away from 6150, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 10:
When dividing 4080 by 638, we get 6 with a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 117317.96
If we subtract 3828 from 4080, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 11:
2520 divided by 638 is 3 with a remainder of 606.
Record the quotient 3 as the next digit in the result. 
Result so far: 117317.963
If we take 1914 away from 2520, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Moving on to step 12:
The number 638 fits into 6060 9 times, leaving a remainder of 318.
The number 9 becomes the next digit in our result. 
Result so far: 117317.9639
Subtract 5742 from 6060 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 13:
If we divide 3180 by 638, we get 4 and a remainder of 628.
Write down 4 as next digit of the result. 
Result so far: 117317.96394
Subtracting 2552 from 3180 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 14:
The number 638 fits into 6280 9 times, leaving a remainder of 538.
The next digit of our result is 9. 
Result so far: 117317.963949
The remainder is 538 after subtracting 5742 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 15:
638 goes into 5380 8 times with a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 117317.9639498
Subtract 5104 from 5380 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 16:
2760 divided by 638 is 4 with a remainder of 208.
Record the quotient 4 as the next digit in the result. 
Result so far: 117317.96394984
Deduct 2552 from 2760 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 117317.96394984 with a remainder of 2.08e-07.
