We look at the division of 91886300 by 399 
Our goal is to divide 91886300 by 399.

Let's proceed to step 1:
399 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 399

On to step 2:
The number 399 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 399

Step 3:
918 divided by 399 is 2 with a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 798 from 918, we get 120.
Grab the next digit (8) from the dividend, add it to 120, then carry on: 1208 / 399

Going ahead to step 4:
1208 divided by 399 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 1197 from 1208, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 399

Going ahead to step 5:
If we divide 116 by 399, we get 0 and a remainder of 116.
Put 0 as the next digit of the answer. 
Result so far: 230.0
The remainder is 116 after subtracting 0 from 116.
Grab the next digit (3) from the dividend, add it to 116, then carry on: 1163 / 399

Step 6:
399 can be fit into 1163 2 times, resulting in a remainder of 365.
Put 2 as the next digit of the answer. 
Result so far: 2302.0
Deduct 798 from 1163 and we're left with 365.
Grab the next digit (0) from the dividend, add it to 365, then carry on: 3650 / 399

Let's proceed to step 7:
399 goes into 3650 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 23029.0
If we take 3591 away from 3650, we end up with 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 399

Step 8:
399 goes into 590 1 times with a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 230291.0
Deduct 399 from 590 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 9:
399 can be fit into 1910 4 times, resulting in a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 230291.4
Subtract 1596 from 1910 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 10:
When dividing 3140 by 399, we get 7 with a remainder of 347.
Record the quotient 7 as the next digit in the result. 
Result so far: 230291.47
Subtracting 2793 from 3140 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 11:
If we divide 3470 by 399, we get 8 and a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 230291.478
Deduct 3192 from 3470 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 12:
399 goes into 2780 6 times with a remainder of 386.
Put 6 as the next digit of the answer. 
Result so far: 230291.4786
Subtract 2394 from 2780 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 13:
If we divide 3860 by 399, we get 9 and a remainder of 269.
Record the quotient 9 as the next digit in the result. 
Result so far: 230291.47869
If we take 3591 away from 3860, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 14:
399 goes into 2690 6 times with a remainder of 296.
The next digit of our result is 6. 
Result so far: 230291.478696
If we take 2394 away from 2690, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 15:
399 can be fit into 2960 7 times, resulting in a remainder of 167.
The next digit of our result is 7. 
Result so far: 230291.4786967
Deduct 2793 from 2960 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.

Let's proceed to step 16:
If we divide 1670 by 399, we get 4 and a remainder of 74.
The next digit of our result is 4. 
Result so far: 230291.47869674
If we subtract 1596 from 1670, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 230291.47869674 with a remainder of 7.4e-08.
