61443931 ÷ 170 
We want to figure out the number of times 61443931 can be divided by 170.

Moving on to step 1:
170 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 170

Moving on to step 2:
61 divided by 170 is 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Grab the next digit (4) from the dividend, add it to 61, then carry on: 614 / 170

On to step 3:
When dividing 614 by 170, we get 3 with a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 510 from 614 leaves us with 104.
Include the next digit (4) from the dividend after 104, then repeat: 1044 / 170

Let's proceed to step 4:
The number 170 fits into 1044 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we take 1020 away from 1044, we end up with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 170

Going ahead to step 5:
170 goes into 243 1 times with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 361.0
Deduct 170 from 243 and we're left with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 170

Advancing to step 6:
170 can be fit into 739 4 times, resulting in a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 3614.0
The remainder is 59 after subtracting 680 from 739.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 170

On to step 7:
The number 170 fits into 593 3 times, leaving a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 36143.0
If we take 510 away from 593, we end up with 83.
Take the next digit (1) from the dividend and append it to 83, then repeat: 831 / 170

Going ahead to step 8:
170 can be fit into 831 4 times, resulting in a remainder of 151.
Use 4 as the next digit of our solution. 
Result so far: 361434.0
Subtracting 680 from 831 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 9:
170 goes into 1510 8 times with a remainder of 150.
The next digit of our result is 8. 
Result so far: 361434.8
Subtract 1360 from 1510 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
If we divide 1500 by 170, we get 8 and a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 361434.88
If we take 1360 away from 1500, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 361434.88 with a balance of 0.14.
