We're dividing 66753955 by 902 
We want to divide 66753955 by 902.

Step 1:
The number 902 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 902

Moving on to step 2:
The number 902 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 902

Let's proceed to step 3:
902 can be fit into 667 0 times, resulting in a remainder of 667.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 667, we end up with 667.
Append the next digit (5) from the dividend to 667 and continue with: 6675 / 902

Let's proceed to step 4:
6675 divided by 902 is 7 with a remainder of 361.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 6314 from 6675 leaves us with 361.
Take the next digit (3) from the dividend and append it to 361, then repeat: 3613 / 902

Step 5:
3613 divided by 902 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtracting 3608 from 3613 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 902

Advancing to step 6:
When dividing 59 by 902, we get 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 740.0
Deduct 0 from 59 and we're left with 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 902

Let's proceed to step 7:
595 divided by 902 is 0 with a remainder of 595.
The number 0 becomes the next digit in our result. 
Result so far: 7400.0
Deduct 0 from 595 and we're left with 595.
Take the next digit (5) from the dividend and append it to 595, then repeat: 5955 / 902

On to step 8:
902 goes into 5955 6 times with a remainder of 543.
Use 6 as the next digit of our solution. 
Result so far: 74006.0
If we subtract 5412 from 5955, we get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 9:
5430 divided by 902 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 74006.6
If we take 5412 away from 5430, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
902 can be fit into 180 0 times, resulting in a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 74006.6
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
902 goes into 1800 1 times with a remainder of 898.
Put 1 as the next digit of the answer. 
Result so far: 74006.601
Deduct 902 from 1800 and we're left with 898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8980, and continue the process.

Advancing to step 12:
8980 divided by 902 is 9 with a remainder of 862.
The number 9 becomes the next digit in our result. 
Result so far: 74006.6019
Deduct 8118 from 8980 and we're left with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Advancing to step 13:
If we divide 8620 by 902, we get 9 and a remainder of 502.
Write down 9 as next digit of the result. 
Result so far: 74006.60199
If we take 8118 away from 8620, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

After the division, we end up with 74006.60199 and a remainder of 0.000502.
