We look at the division of 83631421 by 46 
We want to divide 83631421 by 46.

Step 1:
The number 46 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 46

Moving on to step 2:
83 divided by 46 is 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 37 after subtracting 46 from 83.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 46

Moving on to step 3:
46 can be fit into 376 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 368 from 376 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 46

Step 4:
46 can be fit into 83 1 times, resulting in a remainder of 37.
The next digit of our result is 1. 
Result so far: 181.0
Deduct 46 from 83 and we're left with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 46

Step 5:
If we divide 371 by 46, we get 8 and a remainder of 3.
The next digit of our result is 8. 
Result so far: 1818.0
Deduct 368 from 371 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 46

Step 6:
34 divided by 46 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 18180.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 46

On to step 7:
46 can be fit into 342 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 181807.0
Subtract 322 from 342 to get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 46

Going ahead to step 8:
When dividing 201 by 46, we get 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 1818074.0
If we take 184 away from 201, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
When dividing 170 by 46, we get 3 with a remainder of 32.
The next digit of our result is 3. 
Result so far: 1818074.3
The remainder is 32 after subtracting 138 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
When dividing 320 by 46, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 1818074.36
If we subtract 276 from 320, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
If we divide 440 by 46, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1818074.369
If we subtract 414 from 440, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
46 can be fit into 260 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1818074.3695
If we subtract 230 from 260, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
If we divide 300 by 46, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1818074.36956
Deduct 276 from 300 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 46 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1818074.369565
Subtract 230 from 240 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
100 divided by 46 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1818074.3695652
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 16:
46 goes into 80 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1818074.36956521
Deduct 46 from 80 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 1818074.36956521 with a remaining 3.4e-08.
