We look at the division of 90186458 by 74 
Our goal is to divide 90186458 by 74.

Going ahead to step 1:
74 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 74

On to step 2:
74 can be fit into 90 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 74 from 90 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 74

Advancing to step 3:
74 goes into 161 2 times with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 148 from 161 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 74

Advancing to step 4:
74 can be fit into 138 1 times, resulting in a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 121.0
The remainder is 64 after subtracting 74 from 138.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 74

Moving on to step 5:
If we divide 646 by 74, we get 8 and a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 1218.0
The remainder is 54 after subtracting 592 from 646.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 74

Step 6:
544 divided by 74 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 12187.0
If we subtract 518 from 544, we get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 74

Going ahead to step 7:
When dividing 265 by 74, we get 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 121873.0
Subtracting 222 from 265 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 74

Step 8:
438 divided by 74 is 5 with a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 1218735.0
Subtracting 370 from 438 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
When dividing 680 by 74, we get 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 1218735.9
If we take 666 away from 680, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
If we divide 140 by 74, we get 1 and a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 1218735.91
If we subtract 74 from 140, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
74 can be fit into 660 8 times, resulting in a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 1218735.918
Subtracting 592 from 660 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
74 can be fit into 680 9 times, resulting in a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 1218735.9189
Subtracting 666 from 680 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 74, we get 1 and a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 1218735.91891
The remainder is 66 after subtracting 74 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
When dividing 660 by 74, we get 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 1218735.918918
Subtracting 592 from 660 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 15:
When dividing 680 by 74, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 1218735.9189189
Subtracting 666 from 680 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 16:
The number 74 fits into 140 1 times, leaving a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 1218735.91891891
Deduct 74 from 140 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 1218735.91891891 with a remainder of 6.6e-08.
