We look at the division of 73862943 by 407 
We want to figure out the number of times 73862943 can be divided by 407.

Advancing to step 1:
If we divide 7 by 407, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 407

Step 2:
407 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 407

Step 3:
407 can be fit into 738 1 times, resulting in a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 407 from 738 and we're left with 331.
Fetch the next digit (6) from the dividend, attach it to 331 and continue: 3316 / 407

Advancing to step 4:
The number 407 fits into 3316 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 3256 away from 3316, we end up with 60.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 407

Moving on to step 5:
The number 407 fits into 602 1 times, leaving a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
The remainder is 195 after subtracting 407 from 602.
Fetch the next digit (9) from the dividend, attach it to 195 and continue: 1959 / 407

Advancing to step 6:
If we divide 1959 by 407, we get 4 and a remainder of 331.
Record the quotient 4 as the next digit in the result. 
Result so far: 1814.0
Deduct 1628 from 1959 and we're left with 331.
Grab the next digit (4) from the dividend, add it to 331, then carry on: 3314 / 407

Let's proceed to step 7:
3314 divided by 407 is 8 with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 18148.0
Subtract 3256 from 3314 to get 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 407

On to step 8:
When dividing 583 by 407, we get 1 with a remainder of 176.
Write down 1 as next digit of the result. 
Result so far: 181481.0
Subtracting 407 from 583 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
407 goes into 1760 4 times with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 181481.4
If we take 1628 away from 1760, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
1320 divided by 407 is 3 with a remainder of 99.
The next digit of our result is 3. 
Result so far: 181481.43
If we take 1221 away from 1320, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 11:
407 can be fit into 990 2 times, resulting in a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 181481.432
Subtracting 814 from 990 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 12:
407 can be fit into 1760 4 times, resulting in a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 181481.4324
If we take 1628 away from 1760, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 13:
407 can be fit into 1320 3 times, resulting in a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 181481.43243
The remainder is 99 after subtracting 1221 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 14:
990 divided by 407 is 2 with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 181481.432432
The remainder is 176 after subtracting 814 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 15:
1760 divided by 407 is 4 with a remainder of 132.
Write down 4 as next digit of the result. 
Result so far: 181481.4324324
If we take 1628 away from 1760, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 16:
407 goes into 1320 3 times with a remainder of 99.
Put 3 as the next digit of the answer. 
Result so far: 181481.43243243
The remainder is 99 after subtracting 1221 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Our division results in 181481.43243243 with a remaining 9.9e-08.
