39599636 ÷ 121 
We want to figure out the number of times 39599636 can be divided by 121.

On to step 1:
The number 121 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 121

Advancing to step 2:
If we divide 39 by 121, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 121

Going ahead to step 3:
121 goes into 395 3 times with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 363 from 395 leaves us with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 121

Advancing to step 4:
329 divided by 121 is 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 242 away from 329, we end up with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 121

Going ahead to step 5:
121 goes into 879 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 327.0
If we take 847 away from 879, we end up with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 121

Let's proceed to step 6:
121 can be fit into 326 2 times, resulting in a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 3272.0
Subtracting 242 from 326 leaves us with 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 121

Step 7:
121 can be fit into 843 6 times, resulting in a remainder of 117.
Use 6 as the next digit of our solution. 
Result so far: 32726.0
If we take 726 away from 843, we end up with 117.
Append the next digit (6) from the dividend to 117 and continue with: 1176 / 121

Step 8:
1176 divided by 121 is 9 with a remainder of 87.
The number 9 becomes the next digit in our result. 
Result so far: 327269.0
The remainder is 87 after subtracting 1089 from 1176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
121 goes into 870 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 327269.7
If we subtract 847 from 870, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
121 can be fit into 230 1 times, resulting in a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 327269.71
If we subtract 121 from 230, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 11:
The number 121 fits into 1090 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 327269.719
Deduct 1089 from 1090 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
121 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 327269.719
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
100 divided by 121 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 327269.719
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 327269.719, and the remainder is 0.0001.
