We look at the division of 90107849 by 237 
We're looking to find how many times 237 goes into 90107849.

Let's proceed to step 1:
When dividing 9 by 237, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 237

Moving on to step 2:
The number 237 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 237

Going ahead to step 3:
If we divide 901 by 237, we get 3 and a remainder of 190.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 711 from 901 to get 190.
Take the next digit (0) from the dividend and append it to 190, then repeat: 1900 / 237

Let's proceed to step 4:
237 goes into 1900 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 1896 from 1900 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 237

Moving on to step 5:
When dividing 47 by 237, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 380.0
Deduct 0 from 47 and we're left with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 237

Advancing to step 6:
237 goes into 478 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3802.0
Deduct 474 from 478 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 237

Let's proceed to step 7:
The number 237 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 38020.0
Subtracting 0 from 44 leaves us with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 237

On to step 8:
449 divided by 237 is 1 with a remainder of 212.
Use 1 as the next digit of our solution. 
Result so far: 380201.0
Deduct 237 from 449 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
237 can be fit into 2120 8 times, resulting in a remainder of 224.
Write down 8 as next digit of the result. 
Result so far: 380201.8
If we take 1896 away from 2120, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 10:
2240 divided by 237 is 9 with a remainder of 107.
The number 9 becomes the next digit in our result. 
Result so far: 380201.89
Subtract 2133 from 2240 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 11:
1070 divided by 237 is 4 with a remainder of 122.
The next digit of our result is 4. 
Result so far: 380201.894
Subtract 948 from 1070 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
If we divide 1220 by 237, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 380201.8945
Subtract 1185 from 1220 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
237 goes into 350 1 times with a remainder of 113.
Put 1 as the next digit of the answer. 
Result so far: 380201.89451
Deduct 237 from 350 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 14:
The number 237 fits into 1130 4 times, leaving a remainder of 182.
Write down 4 as next digit of the result. 
Result so far: 380201.894514
If we subtract 948 from 1130, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 15:
1820 divided by 237 is 7 with a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 380201.8945147
Subtracting 1659 from 1820 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 16:
1610 divided by 237 is 6 with a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 380201.89451476
Subtracting 1422 from 1610 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

In conclusion, the division gives 380201.89451476 with a balance of 1.88e-07.
