We divide 43085121 by 39
Our goal is to divide 43085121 by 39.

Let's proceed to step 1:
39 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 39

Going ahead to step 2:
If we divide 43 by 39, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 4 after subtracting 39 from 43.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 39

Moving on to step 3:
39 goes into 40 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 1 after subtracting 39 from 40.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 39

Step 4:
If we divide 18 by 39, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we take 0 away from 18, we end up with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 39

Let's proceed to step 5:
When dividing 185 by 39, we get 4 with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 1104.0
Deduct 156 from 185 and we're left with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 39

Let's proceed to step 6:
When dividing 291 by 39, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 11047.0
Subtract 273 from 291 to get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 39

Let's proceed to step 7:
When dividing 182 by 39, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 110474.0
Subtract 156 from 182 to get 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 39

Let's proceed to step 8:
The number 39 fits into 261 6 times, leaving a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 1104746.0
If we take 234 away from 261, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 39, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1104746.6
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
The number 39 fits into 360 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 1104746.69
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
90 divided by 39 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 1104746.692
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
When dividing 120 by 39, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 1104746.6923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
39 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1104746.6923
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
39 goes into 300 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 1104746.692307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 15:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 1104746.6923076
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 16:
360 divided by 39 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1104746.69230769
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 1104746.69230769, with a leftover of 9e-09.
