Let's divide 64085210 by 161
We want to figure out the number of times 64085210 can be divided by 161.

Going ahead to step 1:
The number 161 fits into 6 0 times, leaving 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 (4) from the dividend, attach it to 6 and continue: 64 / 161

Let's proceed to step 2:
64 divided by 161 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 161

On to step 3:
161 can be fit into 640 3 times, resulting in a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 483 from 640 and we're left with 157.
Append the next digit (8) from the dividend to 157 and continue with: 1578 / 161

Step 4:
161 goes into 1578 9 times with a remainder of 129.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 129 after subtracting 1449 from 1578.
Include the next digit (5) from the dividend after 129, then repeat: 1295 / 161

On to step 5:
161 goes into 1295 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
If we take 1288 away from 1295, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 161

Let's proceed to step 6:
If we divide 72 by 161, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 3980.0
If we take 0 away from 72, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 161

Advancing to step 7:
161 can be fit into 721 4 times, resulting in a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 39804.0
If we take 644 away from 721, we end up with 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 161

Advancing to step 8:
If we divide 770 by 161, we get 4 and a remainder of 126.
Record the quotient 4 as the next digit in the result. 
Result so far: 398044.0
The remainder is 126 after subtracting 644 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
If we divide 1260 by 161, we get 7 and a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 398044.7
The remainder is 133 after subtracting 1127 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 10:
1330 divided by 161 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 398044.78
Deduct 1288 from 1330 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
161 can be fit into 420 2 times, resulting in a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 398044.782
If we take 322 away from 420, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 12:
If we divide 980 by 161, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 398044.7826
Subtracting 966 from 980 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
161 goes into 140 0 times with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 398044.7826
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
161 can be fit into 1400 8 times, resulting in a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 398044.782608
Subtract 1288 from 1400 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
161 can be fit into 1120 6 times, resulting in a remainder of 154.
The next digit of our result is 6. 
Result so far: 398044.7826086
Subtract 966 from 1120 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 16:
The number 161 fits into 1540 9 times, leaving a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 398044.78260869
Subtract 1449 from 1540 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

In conclusion, the division gives 398044.78260869 with a balance of 9.1e-08.
