Let's divide 39609910 by 289
We want to divide 39609910 by 289.

On to step 1:
When dividing 3 by 289, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 289

On to step 2:
When dividing 39 by 289, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 289

On to step 3:
289 can be fit into 396 1 times, resulting in a remainder of 107.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 289 from 396 leaves us with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 289

Step 4:
289 can be fit into 1070 3 times, resulting in a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 867 from 1070, we get 203.
Take the next digit (9) from the dividend and append it to 203, then repeat: 2039 / 289

Moving on to step 5:
The number 289 fits into 2039 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 2023 from 2039 and we're left with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 289

Going ahead to step 6:
169 divided by 289 is 0 with a remainder of 169.
Record the quotient 0 as the next digit in the result. 
Result so far: 1370.0
Deduct 0 from 169 and we're left with 169.
Append the next digit (1) from the dividend to 169 and continue with: 1691 / 289

Step 7:
1691 divided by 289 is 5 with a remainder of 246.
Write down 5 as next digit of the result. 
Result so far: 13705.0
If we subtract 1445 from 1691, we get 246.
Grab the next digit (0) from the dividend, add it to 246, then carry on: 2460 / 289

Advancing to step 8:
When dividing 2460 by 289, we get 8 with a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 137058.0
If we take 2312 away from 2460, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 9:
If we divide 1480 by 289, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 137058.5
If we subtract 1445 from 1480, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
289 can be fit into 350 1 times, resulting in a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 137058.51
Subtracting 289 from 350 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
289 goes into 610 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 137058.512
The remainder is 32 after subtracting 578 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
320 divided by 289 is 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 137058.5121
Subtracting 289 from 320 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
If we divide 310 by 289, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 137058.51211
Deduct 289 from 310 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 137058.51211 with a remainder of 2.1e-05.
