We divide 53691717 by 407
We want to divide 53691717 by 407.

Advancing to step 1:
The number 407 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 407

On to step 2:
407 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 407

Advancing to step 3:
536 divided by 407 is 1 with a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 407 from 536 to get 129.
Grab the next digit (9) from the dividend, add it to 129, then carry on: 1299 / 407

Step 4:
407 goes into 1299 3 times with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1221 from 1299 to get 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 407

Let's proceed to step 5:
The number 407 fits into 781 1 times, leaving a remainder of 374.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtract 407 from 781 to get 374.
Include the next digit (7) from the dividend after 374, then repeat: 3747 / 407

Going ahead to step 6:
407 can be fit into 3747 9 times, resulting in a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 1319.0
Subtracting 3663 from 3747 leaves us with 84.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 407

Step 7:
The number 407 fits into 841 2 times, leaving a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 13192.0
Subtracting 814 from 841 leaves us with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 407

Step 8:
When dividing 277 by 407, we get 0 with a remainder of 277.
The number 0 becomes the next digit in our result. 
Result so far: 131920.0
If we subtract 0 from 277, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 9:
The number 407 fits into 2770 6 times, leaving a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 131920.6
Deduct 2442 from 2770 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
407 can be fit into 3280 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 131920.68
Deduct 3256 from 3280 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.

Moving on to step 11:
If we divide 240 by 407, we get 0 and a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 131920.68
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
407 can be fit into 2400 5 times, resulting in a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 131920.6805
If we take 2035 away from 2400, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 13:
The number 407 fits into 3650 8 times, leaving a remainder of 394.
Record the quotient 8 as the next digit in the result. 
Result so far: 131920.68058
The remainder is 394 after subtracting 3256 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 14:
When dividing 3940 by 407, we get 9 with a remainder of 277.
Record the quotient 9 as the next digit in the result. 
Result so far: 131920.680589
If we subtract 3663 from 3940, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 15:
If we divide 2770 by 407, we get 6 and a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 131920.6805896
If we take 2442 away from 2770, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 16:
407 goes into 3280 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 131920.68058968
Deduct 3256 from 3280 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.

In conclusion, the division gives 131920.68058968 with a balance of 2.4e-08.
