51223186 ÷ 602 
We want to figure out the number of times 51223186 can be divided by 602.

Advancing to step 1:
602 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 602

Advancing to step 2:
51 divided by 602 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 602

On to step 3:
602 can be fit into 512 0 times, resulting in a remainder of 512.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 512 to get 512.
Bring next digit (2) of the dividend behind the 512 and repeat the process: 5122 / 602

Going ahead to step 4:
602 goes into 5122 8 times with a remainder of 306.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 306 after subtracting 4816 from 5122.
Bring next digit (3) of the dividend behind the 306 and repeat the process: 3063 / 602

Step 5:
When dividing 3063 by 602, we get 5 with a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Deduct 3010 from 3063 and we're left with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 602

Going ahead to step 6:
602 can be fit into 531 0 times, resulting in a remainder of 531.
Put 0 as the next digit of the answer. 
Result so far: 850.0
Deduct 0 from 531 and we're left with 531.
Fetch the next digit (8) from the dividend, attach it to 531 and continue: 5318 / 602

Step 7:
5318 divided by 602 is 8 with a remainder of 502.
The next digit of our result is 8. 
Result so far: 8508.0
Subtracting 4816 from 5318 leaves us with 502.
Fetch the next digit (6) from the dividend, attach it to 502 and continue: 5026 / 602

On to step 8:
When dividing 5026 by 602, we get 8 with a remainder of 210.
Use 8 as the next digit of our solution. 
Result so far: 85088.0
Subtract 4816 from 5026 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 9:
When dividing 2100 by 602, we get 3 with a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 85088.3
Deduct 1806 from 2100 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
602 can be fit into 2940 4 times, resulting in a remainder of 532.
The number 4 becomes the next digit in our result. 
Result so far: 85088.34
Subtracting 2408 from 2940 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 11:
5320 divided by 602 is 8 with a remainder of 504.
The number 8 becomes the next digit in our result. 
Result so far: 85088.348
If we take 4816 away from 5320, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 12:
5040 divided by 602 is 8 with a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 85088.3488
Deduct 4816 from 5040 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

In conclusion, the division gives 85088.3488 with a balance of 0.00224.
