43470702 ÷ 661 
We want to divide 43470702 by 661.

Advancing to step 1:
The number 661 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 661

Going ahead to step 2:
43 divided by 661 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 661

Let's proceed to step 3:
The number 661 fits into 434 0 times, leaving a remainder of 434.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 434 and we're left with 434.
Bring next digit (7) of the dividend behind the 434 and repeat the process: 4347 / 661

Let's proceed to step 4:
When dividing 4347 by 661, we get 6 with a remainder of 381.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3966 from 4347 to get 381.
Bring next digit (0) of the dividend behind the 381 and repeat the process: 3810 / 661

Going ahead to step 5:
If we divide 3810 by 661, we get 5 and a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we take 3305 away from 3810, we end up with 505.
Take the next digit (7) from the dividend and append it to 505, then repeat: 5057 / 661

Going ahead to step 6:
When dividing 5057 by 661, we get 7 with a remainder of 430.
The next digit of our result is 7. 
Result so far: 657.0
Deduct 4627 from 5057 and we're left with 430.
Bring next digit (0) of the dividend behind the 430 and repeat the process: 4300 / 661

Advancing to step 7:
If we divide 4300 by 661, we get 6 and a remainder of 334.
Put 6 as the next digit of the answer. 
Result so far: 6576.0
Subtracting 3966 from 4300 leaves us with 334.
Grab the next digit (2) from the dividend, add it to 334, then carry on: 3342 / 661

Let's proceed to step 8:
The number 661 fits into 3342 5 times, leaving a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 65765.0
The remainder is 37 after subtracting 3305 from 3342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
370 divided by 661 is 0 with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 65765.0
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 10:
661 goes into 3700 5 times with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 65765.05
The remainder is 395 after subtracting 3305 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 11:
661 can be fit into 3950 5 times, resulting in a remainder of 645.
The number 5 becomes the next digit in our result. 
Result so far: 65765.055
If we subtract 3305 from 3950, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

After the division, we end up with 65765.055 and a remainder of 0.0645.
