39979766 ÷ 602 
Our goal is to divide 39979766 by 602.

Advancing to step 1:
The number 602 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 602

On to step 2:
The number 602 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 602

Step 3:
The number 602 fits into 399 0 times, leaving a remainder of 399.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Include the next digit (7) from the dividend after 399, then repeat: 3997 / 602

Let's proceed to step 4:
3997 divided by 602 is 6 with a remainder of 385.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3612 from 3997 to get 385.
Append the next digit (9) from the dividend to 385 and continue with: 3859 / 602

Moving on to step 5:
602 can be fit into 3859 6 times, resulting in a remainder of 247.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 3612 from 3859, we get 247.
Append the next digit (7) from the dividend to 247 and continue with: 2477 / 602

Going ahead to step 6:
602 goes into 2477 4 times with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 664.0
The remainder is 69 after subtracting 2408 from 2477.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 602

Going ahead to step 7:
602 can be fit into 696 1 times, resulting in a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 6641.0
The remainder is 94 after subtracting 602 from 696.
Take the next digit (6) from the dividend and append it to 94, then repeat: 946 / 602

Step 8:
602 can be fit into 946 1 times, resulting in a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 66411.0
If we take 602 away from 946, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 9:
3440 divided by 602 is 5 with a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 66411.5
Subtract 3010 from 3440 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
4300 divided by 602 is 7 with a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 66411.57
Subtract 4214 from 4300 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
860 divided by 602 is 1 with a remainder of 258.
The number 1 becomes the next digit in our result. 
Result so far: 66411.571
Deduct 602 from 860 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 12:
If we divide 2580 by 602, we get 4 and a remainder of 172.
Write down 4 as next digit of the result. 
Result so far: 66411.5714
Subtracting 2408 from 2580 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 13:
If we divide 1720 by 602, we get 2 and a remainder of 516.
The number 2 becomes the next digit in our result. 
Result so far: 66411.57142
If we take 1204 away from 1720, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 14:
The number 602 fits into 5160 8 times, leaving a remainder of 344.
Put 8 as the next digit of the answer. 
Result so far: 66411.571428
Deduct 4816 from 5160 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 15:
When dividing 3440 by 602, we get 5 with a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 66411.5714285
The remainder is 430 after subtracting 3010 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 16:
602 goes into 4300 7 times with a remainder of 86.
Write down 7 as next digit of the result. 
Result so far: 66411.57142857
The remainder is 86 after subtracting 4214 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 66411.57142857 with a remaining 8.6e-08.
