83911989 ÷ 464 
We want to divide 83911989 by 464.

On to step 1:
When dividing 8 by 464, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 464

Step 2:
If we divide 83 by 464, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 464

Advancing to step 3:
If we divide 839 by 464, we get 1 and a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 464 from 839, we get 375.
Grab the next digit (1) from the dividend, add it to 375, then carry on: 3751 / 464

Let's proceed to step 4:
If we divide 3751 by 464, we get 8 and a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 3712 away from 3751, we end up with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 464

Going ahead to step 5:
If we divide 391 by 464, we get 0 and a remainder of 391.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Subtracting 0 from 391 leaves us with 391.
Grab the next digit (9) from the dividend, add it to 391, then carry on: 3919 / 464

On to step 6:
464 can be fit into 3919 8 times, resulting in a remainder of 207.
The next digit of our result is 8. 
Result so far: 1808.0
Deduct 3712 from 3919 and we're left with 207.
Take the next digit (8) from the dividend and append it to 207, then repeat: 2078 / 464

On to step 7:
When dividing 2078 by 464, we get 4 with a remainder of 222.
Write down 4 as next digit of the result. 
Result so far: 18084.0
If we subtract 1856 from 2078, we get 222.
Grab the next digit (9) from the dividend, add it to 222, then carry on: 2229 / 464

Step 8:
When dividing 2229 by 464, we get 4 with a remainder of 373.
Write down 4 as next digit of the result. 
Result so far: 180844.0
If we subtract 1856 from 2229, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 9:
If we divide 3730 by 464, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 180844.8
Deduct 3712 from 3730 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
If we divide 180 by 464, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 180844.8
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
When dividing 1800 by 464, we get 3 with a remainder of 408.
Record the quotient 3 as the next digit in the result. 
Result so far: 180844.803
If we subtract 1392 from 1800, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 12:
If we divide 4080 by 464, we get 8 and a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 180844.8038
If we take 3712 away from 4080, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 13:
464 can be fit into 3680 7 times, resulting in a remainder of 432.
Put 7 as the next digit of the answer. 
Result so far: 180844.80387
The remainder is 432 after subtracting 3248 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 14:
464 can be fit into 4320 9 times, resulting in a remainder of 144.
The next digit of our result is 9. 
Result so far: 180844.803879
The remainder is 144 after subtracting 4176 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 15:
1440 divided by 464 is 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 180844.8038793
Subtract 1392 from 1440 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
464 goes into 480 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 180844.80387931
If we subtract 464 from 480, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 180844.80387931 with a balance of 1.6e-08.
