We look at the division of 85769121 by 407 
We're looking to find how many times 407 goes into 85769121.

Moving on to step 1:
407 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 407

Going ahead to step 2:
85 divided by 407 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 407

Advancing to step 3:
857 divided by 407 is 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 814 from 857 to get 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 407

On to step 4:
If we divide 436 by 407, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 29 after subtracting 407 from 436.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 407

Moving on to step 5:
The number 407 fits into 299 0 times, leaving a remainder of 299.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
Subtracting 0 from 299 leaves us with 299.
Append the next digit (1) from the dividend to 299 and continue with: 2991 / 407

Moving on to step 6:
407 goes into 2991 7 times with a remainder of 142.
The number 7 becomes the next digit in our result. 
Result so far: 2107.0
If we subtract 2849 from 2991, we get 142.
Grab the next digit (2) from the dividend, add it to 142, then carry on: 1422 / 407

Step 7:
1422 divided by 407 is 3 with a remainder of 201.
Put 3 as the next digit of the answer. 
Result so far: 21073.0
Subtracting 1221 from 1422 leaves us with 201.
Grab the next digit (1) from the dividend, add it to 201, then carry on: 2011 / 407

Moving on to step 8:
When dividing 2011 by 407, we get 4 with a remainder of 383.
The number 4 becomes the next digit in our result. 
Result so far: 210734.0
The remainder is 383 after subtracting 1628 from 2011.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 9:
3830 divided by 407 is 9 with a remainder of 167.
The next digit of our result is 9. 
Result so far: 210734.9
Subtract 3663 from 3830 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 10:
407 can be fit into 1670 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 210734.94
The remainder is 42 after subtracting 1628 from 1670.
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:
407 goes into 420 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 210734.941
If we take 407 away from 420, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
407 can be fit into 130 0 times, resulting in a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 210734.941
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 13:
407 goes into 1300 3 times with a remainder of 79.
The next digit of our result is 3. 
Result so far: 210734.94103
If we subtract 1221 from 1300, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 14:
407 can be fit into 790 1 times, resulting in a remainder of 383.
The next digit of our result is 1. 
Result so far: 210734.941031
Subtract 407 from 790 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 15:
407 can be fit into 3830 9 times, resulting in a remainder of 167.
Record the quotient 9 as the next digit in the result. 
Result so far: 210734.9410319
Deduct 3663 from 3830 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 16:
When dividing 1670 by 407, we get 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 210734.94103194
Subtract 1628 from 1670 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 210734.94103194 and a remainder of 4.2e-08.
