84398131 ÷ 46 
Let's see how many times 46 fits into 84398131.

On to step 1:
The number 46 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 46

Moving on to step 2:
The number 46 fits into 84 1 times, leaving a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 46 away from 84, we end up with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 46

Advancing to step 3:
The number 46 fits into 383 8 times, leaving a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 368 from 383, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 46

Going ahead to step 4:
If we divide 159 by 46, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 183.0
Deduct 138 from 159 and we're left with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 46

Advancing to step 5:
When dividing 218 by 46, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1834.0
The remainder is 34 after subtracting 184 from 218.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 46

Moving on to step 6:
When dividing 341 by 46, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 18347.0
Subtract 322 from 341 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 46

Let's proceed to step 7:
If we divide 193 by 46, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 183474.0
Subtract 184 from 193 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 46

Moving on to step 8:
When dividing 91 by 46, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1834741.0
Deduct 46 from 91 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
450 divided by 46 is 9 with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 1834741.9
The remainder is 36 after subtracting 414 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
46 can be fit into 360 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 1834741.97
Subtract 322 from 360 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
380 divided by 46 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 1834741.978
If we subtract 368 from 380, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
46 goes into 120 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1834741.9782
The remainder is 28 after subtracting 92 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
The number 46 fits into 280 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 1834741.97826
Subtract 276 from 280 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
The number 46 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1834741.97826
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
46 goes into 400 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1834741.9782608
Deduct 368 from 400 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
46 can be fit into 320 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 1834741.97826086
The remainder is 44 after subtracting 276 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 1834741.97826086, with a leftover of 4.4e-08.
